The paper sums up Riemann s resuls on he Zea funcion, and on he coun of he prime numbers, wih a few connecing words, and no proofs/explanaions. Aemps o wrie he book were made by Tichmarsh, and by Edwards, bu none followed hrough Riemann s wriing. Only by saying faihful o Riemann s developmen of he Zea funcion we can Ge o he origin and meaning of he Riemann Hypohesis, Correc he facoriaion error, Apply Riemann s Formula for he Coun of he Primes, Acquire he ools needed for he Hypohesis Proof In 006, I aemped o wrie ha book, [Dan], and his is an exensive revision of ha aemp. 0.

Riemann obained he erroneous facoriaion ( /) ξ() = ξ + = / n= αn ha does no produce he Logarihmic inegral series erm. Already in 860, Genocchi poined ou ha he formula should use ξ. = 0 9
10 Gauge Insiue Journal, Volume 5, No 4, November 009 Bu ha only divered aenion from he error in he facors of he produc, and he main problem seemed o be ha a derivaion was missing. In 893, Hadamard supplied he derivaion and obained ξ() = ξ(0), ρ where he ρ 's are he eros of ξ (). Hadamard formula does no exhibi he connecion o he α n 's, and so far as I can ell, he connecion o he Logarihmic inegral series in he formula for he coun of he primes, was never made. Indeed, o make ha connecion, one has o follow hrough he whole paper. Thus, producing he correc derivaions and resuls of he Zea paper amouns o execuion of he book ha is oulined in he Zea paper. ρ I use common noaions and erms such as = x + iy no s = σ + iτ w(), no s () s Γ () no Π( s ). "eros of ξ " no "roos of he equaion ξ () = 0." Oherwise, Riemann's noaions are kep unchanged. 0
11 Gauge Insiue Journal, Volume 5, No 4, November 009 The Coun of Prime Numbers. Gauss approximaion In his 859 Zea Paper, Riemann's aim was...o repor on a sudy of he frequency wih which prime numbers occur. A opic ha seems worhy of such reporing, because of he ineres shown in i by Gauss and Dirichle over many years. Gauss (849) compued u= u= du log u o approximae π (), he Number of Primes <.

13 Gauge Insiue Journal, Volume 5, No 4, November 009 Zea Series in Re >. The Euler Produc For Re >, Riemann wroe: ζ( ) n = p...my saring poin was he observaion of Euler ha he produc equals / p= prime p, n= nauraln where p ranges over all he prime numbers, andn over all he naural numbers.

14 Gauge Insiue Journal, Volume 5, No 4, November 009 he funcion of he complex variable, defined by hese wo expressions when hey converge. Proof: Euler's produc formula, defined for k =, 3,... by = , k k k k 3 n k k k k 3 5 p can be exended o complex numbers wih Re >, because Thus, in Re >. x n n n= naural n= naural ζ() = n / p. n= naural p= prime For a proof ha he equaliy beween he sum and he produc in Euler Produc Formula holds for complex numbers, see [Kara], or [Ed] 4
15 Gauge Insiue Journal, Volume 5, No 4, November Zea Inegral in Re > 3. Gamma Inegral in Re > 0 Proof: For x > 0, Euler s inegral, can be wrien as For he firs inegral, Γ () = = = 0 = = 0+ e e d d = = d + d. e e = 0+ = = = = x x lim x d d = = e x = 0+ x x 0+ = 0+ = 0+. Therefore he firs inegral converges uniformly for any x δ > 0. For he second inegral, 5
16 Gauge Insiue Journal, Volume 5, No 4, November 009 = = x d = e = = Inegraing by pars, e d = x = = / e = x = ( e ) + ( x ) d. e = = x = = / e = x 3 = + ( x ) ( e ) + ( x ) ( x ) d e e =.. Evenually, afer [ x ] such inegraions, he power of in he inegrand becomes x [ x], and we have = = ( x )...( x [ x]) d < ( x )...( x [ x]) d < [ x] + x e e = = Therefore, he Gamma inegral is defined, and converges uniformly for x > Gamma for any Γ () is exended for any by n! n Γ () = lim n ( + )( + )...( + n ) 6
17 Gauge Insiue Journal, Volume 5, No 4, November 009 = n lim ( + )( + / )...( + / n ) n This is analyic for any excep for he poles a = 0,,, Zea Inegral in x > For x >, ζ() Riemann wroe: and = = e = 0 d = = 0 = () e = Γ n= naural n / p= prime p = 0 e d d converge only when Re >. However, i is easy o find for ζ () an expression ha holds for any. Firs of all, by applying he equaion = = 0 n e d = Γ() n 7
18 Gauge Insiue Journal, Volume 5, No 4, November 009 Proof: we ge = Γ ()() ζ = d. e = 0 By 3., for x > 0, Euler's Gamma funcion is By he change of variable u Tha is, for n =,, 3,... N, Γ () = u= u= 0 = n, Γ () = n u e u du = = 0 = 0 e n d = Γ () = d, e = Γ () = d, e = 0..., = Γ () = d. N N e = 0 Therefore, summing his equaliies, for x > 0, =.. N N e e e = 0. Γ () = + +. d 8
19 Gauge Insiue Journal, Volume 5, No 4, November 009 Since converges only for x >, hen, leing N, we n n= obain for x >, = N N e e e = 0. Γ ( ) = lim d Uniform convergence of... e + e + = e for δ > 0, allows bringing he limi in, and summing under he inegral sign. Thus, for x >, The inegral, can be wrien as For he second inegral = Γ ( ) = d. e = 0 = e = 0+ d = = d + d e. e = 0+ = 9
20 Gauge Insiue Journal, Volume 5, No 4, November 009 = = x = x d = d d / / / e ( e )( e + ) e = = = The las inegral converges similarly o = d, in 3.. e = For he firs inegral, = = x d = d e e = 0+ = 0+ = = x d e e. = 0+ The inegral diverges in 0 < x, and converges only in x >. Therefore, for x >, = ζ() = d Γ () e = 0. 0

22 Gauge Insiue Journal, Volume 5, No 4, November 009 clockwise around a domain ha conains he singulariy a = 0, bu none of he singulariies a = πin, for n =,,3... To define he muli-valued funcion we choose he branch of ha is real for The inegral equals ( )log( ) ( ) e λ λ =, log( λ) λ < 0. = = 0 iπ iπ ( ) ( e e ) d, e where he inegraion pah is along he real axis. Thus, we obain + i0 i0 ( λ) sin πγ ()() ζ = i dλ. e λ PROOF:
23 Gauge Insiue Journal, Volume 5, No 4, November The Inegraion Pah To evaluae he inegral we choose a pah ha λ= + iδ ( λ) dλ, λ e λ= iδ runs from λ = iδ o λ = δ iδ, along λ = iδ. runs from λ = δ iδ o λ = δ + iδ, encircling = 0 along iθ iθ λ = δ e εe. runs from λ = δ + iδ o λ = + iδ, along λ = + iδ. Then, he inegral equals λ = δ iδ λ = δ + iδ λ = + iδ ( λ) ( λ) ( λ) dλ+ dλ+ dλ λ λ λ e e e. λ= iδ λ= δ iδ λ= δ+ iδ To say in he same branch of log( λ), we should no cross he cu along he posiive x axis. 3
24 Gauge Insiue Journal, Volume 5, No 4, November For δ 0, he Firs Inegral e = iπ e = 0+ d Proof: For he firs inegral, we roae [ iδ] clockwise, muliplying i by o obain Tha is, Therefore, e i π [ iδ]. i λ = [ iδ] = [ iδ] e π. iπ iπ ( λ) = ([ iδ] e ) = e [ iδ] and we have λ = δ iδ ( λ) = iπ ( iδ) λ = λ iδ e e λ= iδ = δ d e d. Since cosδ, we have, e e iδ e + i δ + iδ iδ + ( e )( e ) ( e ) e iδ e 4

Therefore, by Lebesgue Dominan Convergence, as δ 0, firs inegral e = iπ e = 0+ d. 4.4 For δ 0, and x >, he Second Inegral 0 Proof: In he second inegral, and λ = δ ε λ= δ+ iδ θ= π x ( λ) ε dλ iθ exp( εe ) εdθ. λ e λ= δ iδ θ= 0 To apply Lebesgue Dominan Convergence, we need o confirm ha as ε 0, x ε i exp( εe θ ) 0. We will avoid differeniaing square roos by showing ha 5

28 Gauge Insiue Journal, Volume 5, No 4, November 009 For he hird inegral we roae [ + iδ] couner-clockwise, muliplying i by o obain Hence, i e π [ + iδ]. λ = [ + iδ] = [ + iδ] e iπ and we have iπ iπ ( λ) = ([ + iδ] e ) = e [ + iδ] λ = + iδ ( λ) = iπ ( + iδ) λ = λ + iδ e e λ= δ+ iδ = δ d e d Thus, by Lebesgue Dominan Convergence, as δ 0, Third Inegral e = iπ e = 0+ d. 4.6 The Pah-Inegral Formula 4.

Since i equals Zea in he half plane x >, i is he analyic coninuaion of Zea o he complex plane for any. 4.7 A Second pah Inegral Formula for Zea Proof: + i0 i 0 Γ( ) ( λ) ζ() = dλ. πi e λ By 4., + i0 i0 ( λ) ζ() = dλ sin( i π)() Γ. e λ 9

Γ( ) has simple poles a =,, 3..., bu only = is a pole of , or 3 + i0 i0 ( λ) i dλ sin( π) Γ( ). e λ I follows ha he inegral + i0 i0 ( λ) dλ e λ has eros ha cancel he poles a =, 3..., Zea has only one pole a =, and is finie for all. 30
31 Gauge Insiue Journal, Volume 5, No 4, November Zea has eros a = n for n =,,3... Proof: The Bernoulli numbers are defined by B n e = n= 0 B n n! n ha converges in < π. We have and ( ) ( ) =, n + ζ n B n + n B n + = 0 Thus, Zea has eros a for n =,,3... = n 3
32 Gauge Insiue Journal, Volume 5, No 4, November The Zea Funcional Equaion 5. sin πγ ()() ζ = ( π)[( i) + i ]{ } Riemann wroe 3 If x < 0, we inegrae along a clockwise-oriened pah around he complemenary domain in he complex plane. Then, he inegral is infiniesimal, because i is over values ha have infiniely large modulus. In he complemenary domain, he inegrand has singulariies only a λ =± πin, for n =,,3... Therefore, he inegral equals he sum of he clockwiseoriened pah- inegrals around hese singulariies. Since he clockwise-oriened pah-inegral around a singulariy = πin is we have ( πi)( πin), sin ()() ( ) [( ) π ζ π n i i Γ = + ]. n 3
33 Gauge Insiue Journal, Volume 5, No 4, November 009 Proof: By 4., we have + i0 i0 ( λ) sin πγ ()() ζ = i dλ e λ We will evaluae he inegral along a clockwise-oriened pah around he complemenary domain. By he Residue Theorem, he clockwise-oriened inegral equals e λ λ πin = ε ( λ) dλ ( λ) ( λ) ( πi)res = πi lim ( λ πin) λ e By L'Hospial, λ πin λ λ= πin e ( λ πin) lim = lim =. λ e e λ πin λ λ πin Hence, around he singulariy he inegral equals λ = πin, λ πin ( πi) lim ( λ) = ( πi)( πin). Similarly, around he singulariy 33
34 Gauge Insiue Journal, Volume 5, No 4, November 009 λ = πin, he inegral equals ( πi)( πin). The inegral around he complemenary domain is he sum of he inegrals around all he singulariies and i equals Thus, n= = ( πi) [( πin) + ( πin) ] = i( π) [( i) + ( i) ] n n = { } 3 sin πγ ( ) ζ( ) = ( π) [( i) + i ] Zea Funcional Equaion / Define η() π Γ ( /)() ζ.

35 Gauge Insiue Journal, Volume 5, No 4, November 009 Proof: By using known properies of Γ () we obain he following relaion beween ζ () and ζ( ) By secion 5., Pu and π / Γ ( /) ζ( ) is unchanged if replaces. { } 3 sin πγ ( ) ζ( ) = ( π) [( i) + i ] ζ = ( ), 3 [( i) + i ] = i( i) i( i) log( i ) log i = ie [ e ] ( i π/) ( i π/) π = ie [ e ] = sin Then, Subsiue and sin πγ ()() ζ = π sin( π /)( ζ ). π sin( π / ) =, Γ ( /) Γ ( /) π sin( π) Γ ( ) =.
