1 Commun. Koren Mth. So , No. 1, pp A STUDY OF Q-CONTIGUOUS FUNCTION RELATIONS Hrsh Vrdhn Hrsh, Yong Sup Kim, Medht Ahmed Rkh, nd Arjun Kumr Rthie Astrt. In 181, Guss otined fifteen ontiguous funtions reltions. Lter on, 1847, Henie gve their -nlogue. Reently, good progress hs een done in finding more ontiguous funtions reltions y employing results due to Guss. In 1999, Cho et l. hve otined 4 new nd interesting ontiguous funtions reltions with the help of Guss s 15 ontiguous reltions. In ft, suh type of 7 reltions exists nd therefore the rest 48 ontiguous funtions reltions hve very reently een otined y Rkh et l.. Thus, the pper is in ontinution of the pper [16] pulished in Computer & Mthemtis with Applitions , In this pper, first we otined 15 -ontiguous funtions reltions due to Henie y following different method nd then with the help of these 15 -ontiguous funtions reltions, we otin 7 new nd interesting - ontiguous funtions reltions. These -ontiguous funtions reltions hve wide pplitions. 1. Introdution The study of si hypergeometri series -series or -hypergeometri series essentilly strted in 1748 when Euler [5], onsidered the infinite produt ; 1 1 k+1 1 s generting funtion of pn, the numer of k0 prtitions of positive integer n into positive integers. One hundred yers lter, the si hypergeometri series uired n independent sttus when Heine [5], onverted simple oservtion tht 1.1 lim into systemti theory of si hypergeometri series prllel to the theory of Guss hypergeometri series. Reeived April 18, 015; Revised Novemer 18, Mthemtis Sujet Clssifition. 33C05, 33D15.

2 66 H. V. HARSH, Y. S. KIM, M. A. RAKHA, AND A. K. RATHIE The si hypergeometri series hve mny signifint pplitions in severl res of pure nd pplied mthemtis inluding the theory of prtitions, omintoril identities, numer theory, finite vetor spes, Lie theory, mthemtil physis nd sttistis. -integrls re the most ommon pplitions etween -series, Lie lgers nd their root systems. In 181, Guss [6], presented to the Royl Soiety of Sienes t Göttingen his fmous pper Guss 1813 in whih he onsidered the infinite series z z z 3 +, s funtion of,,,z, where it is ssumed tht 0, 1,,..., so tht no zero ftors pper in the denomintors of the terms of the series. He showed tht the series onverges solutely for z < 1, nd for z 1 when R > 0, gve its ontiguous reurrene reltions, nd derived his fmous formul 1.3 F,;;1 ΓΓ, R > 0, Γ Γ for the sum of his series when z 1 nd R > 0. Although Guss used the nottion F,,,z for his series, it is now ustomry to use F,;;z or either of the nottions 1.4 F 1,;;z or F 1 [, for his series nd for its sum when it onverges, euse these nottions seprte the numertor prmeters, from the denomintor prmeter nd the vrile z. Two hypergeometri funtions with the sme rgument z re sid to e ontiguous if their prmeters, nd differ y integers. Guss derived nlogous reltions etween F 1 [,;;z] nd ny two ontiguous hypergeometris in whih prmeter hs een hnged y ±1. Rinville [14] generlized this to ses with more prmeters. Applitions of ontiguous reltions rnge from the evlution of hypergeometri series to the derivtion of summtion nd trnsformtion formuls for suh series, they n e used to evlute hypergeometri funtion tht is ontiguous to hypergeometri series whih n e stisftorily evluted. Contiguous reltions re lso used to mke orrespondene etween Lie lgers nd speil funtions. The orrespondene yields formuls of speil funtions [13]. Guss [6] defined s ontiguous to F 1,;;z or simply F,;;z eh of the six funtions otined y inresing or deresing one of the prmeters y unity. He lso proved tht etween F nd ny two of its ontiguous funtions, there exists liner reltion with oeffiients t most liner nd otined his fifteen interesting nd useful results [8]. ;z ],
3 A STUDY OF Q-CONTIGUOUS FUNCTION RELATIONS 67 Thirty three yers fter Guss s pper, Heine [7], introdued the series z z +, where it is ssumed tht 0, 1,,.... This series onverges solutely for z < 1 when < 1 nd it tends t lest term-wise to Guss series s 1, euse of 1.1. The series 1.5 is usully lled Heine s series or, in view of the se, the si hypergeometri series or -hypergeometri series. Anlogous to Guss nottion, Heine [5], used the nottion Φ,,,,z for his series. It is now ustomry to define the si hypergeometri series y 1.6 where Φ,;;,z or Φ 1,;;,z [ ], ; n ; n or Φ 1 ;,z z n, ; n ; n 1.7 ; n n0 { 1, n 0, n 1, n 1,,..., is the -shifted ftoril nd it is ssumed tht m for m 0,1,... Some other nottions tht hve een used for the produt ; n re,n, [] n nd even n when 1.7 is not used nd the se is not displyed. Generlizing Heine s series, we shll define n r Φ s si hypergeometri series y rφ s 1,,..., r ; 1,,..., s ;,z [ ] 1, r Φ,..., r s ;,z 1,..., s 1 ; n ; n r ; [ n 1 n ] 1+s r n z n 1 ; n ; n s ; n n0 with n nn 1, where 0 when r > s+1. For more detil, see [5]. We lso define 1.8 ; 1 k k0 for < 1. Sine produts of -shifted ftorils our so often, to simplify them we shll freuently use the more ompt nottions ,,..., m ; n 1 ; n ; n m ; n, 1,,..., m ; 1 ; ; m ;, 1 n n+1 n 1 n,

[17] re-estlished fifteen interesting three-term reltions for the 1 series y the method of ompring oeffiients. In suh reltions, their limiting ses reover Guss fifteen ontiguous reltions for F 1 series. The pper is orgnized s follows. In Setion, fifteen -ontiguous funtion reltions due to Henie [7] will e derived y nother method. In Setion 3, we estlish 4 -ontiguous funtion reltions nd in Setion 4 s n pplition of our results, we otined further 48 -ontiguous reltions. In Setion 5, speil ses of our results.13.7, nd re given. Finlly, s n pplition we otin 18 -summtion formuls in losed forms whih will e given in Setion 6. The results derived in this pper re simple, interesting, esily estlished nd my e useful..
