1 Hardy-Littlwood Conjctur and Excptional ral Zro JinHua Fi ChangLing Company of Elctronic Tchnology Baoji Shannxi P.R.China Abstract. In this papr, w assum that Hardy-Littlwood Conjctur, w got a bttr uppr bound of th xcptional ral zro for a class of modul. Kyword. Hardy-Littlwood Conjctur, Excptional ral Zro MR000 Subjct Classification P3, M0 In this papr, w rval th rlationship btwn Hardy-Littlwood Conjctur and th xcptional ral zro. Assum that Hardy-Littlwood Conjctur, w obtaind a good rsults of th xcptional ral zro. In this papr, I gnraliz th rsults of my papr An Application of Hardy-Littlwood Conjctur. is th prim numbr and 3 mod 4 is improvd to is odd suar-fr and 3 mod 4. w know that th modul of th xcptional primitiv ral charactr ar suar-fr whn is odd positiv intgr. First, w giv Hardy-Littlwood Conjctur. Hardy-Littlwood Conjctur. hav 3 p,p N p +p N Whn N is vn intgr and N 6, w N N ϕn p log N p N

2 whr p, p, p ar th prim numbrs, ϕn is Eulr function. Undr th abov conjctur, w hav th following thorm Thorm. Lt is odd suar-fr and 3 mod 4, it has xcptional ral charactr χ, and its Dirichlt Ls, χ function has an xcptional ral zro β. If Hardy-Littlwood Conjctur is corrct, thn thr is a positiv constant c, w hav β c log Now, w do som prparation work. Lmma. Assuming that th Hardy-Littlwood Conjctur. Lt n is any positiv intgr, is odd intgr and larg sufficintly, thn 3 p,p n p +p n n d ϕ log n whr d 3 p p and p, p, p ar th prim numbrs. Proof. By Hardy-Littlwood Conjctur, whn N is larg sufficintly, w hav N N ϕn p log N p N 3 p,p N p +p N

3 bcaus p N p 3 p p and n ϕn p n p p p p p ϕ W choos N n, This complts th proof of Lmma. Lmma. Lt m is positiv intgr and n is intgr, thn m { kn m if n 0 mod m m 0 othrwis k whr x πix. Th lmma is obvious Lmma 3. Lt c b th positiv constant. if a,, thn πx;, a Lix ϕ χa x u β ϕ log u du + O x xp c log x whn thr is an xcptional charactr χ modulo and β is th concomitant zro. Whr Lix x du and xpx x log u Th lmma 3 follows from th Rfrncs [], Corollary.0 of th pag 38 3

Th lmma 4 follows from th Rfrncs [], th pag 47. Lmma 5. if m is odd suar-fr and χ is a primitiv ral charactr modulo m, thn { m if m mod 4 τχ i m if m 3 mod 4 Th lmma 5 follows from th Rfrncs [], th thorm 3.3 of th pag 49. Lmma 6. W giv th valu of two sums, thy ar usd in th proof of th Thorm. k a a, ak k 4 a a, ak bk b b,

Whn k, w hav pk p, pk + Olog a a, ak + Olog p a by Lmma 3 and Lmma 4, th abov formula a a, ak Lix ϕ χa x u β ϕ log u du + O x xp c log x +Olog 6
