高斯超几何级数的某些值与一族代数曲线

Certain values of Gaussian hypergeometric series and a family of algebraic curves

Rupam Barman, Gautam Kalita

摘要:

设$λ\in \mathbb{Q}\setminus \{0, -1\}$和$l \geq 2$。用$C_{l,λ}$表示$\mathbb{Q}$上的非奇异射影代数曲线,其仿射方程由$$y^l=(x-1)(x^2+λ).$$给出。本文给出了有限域上$C_{l, λ}$上的点数与高斯超几何级数之间的关系。我们还给出了McCarthy(2010)的一个结果的另一个证明。我们发现了${_{3}}F_2$和${_{2}}F_1$高斯超几何级数的一些特殊值。最后我们估计了${_{3}}F_2(4)$的值,推广了Ono(1998)的一个结果.

英文摘要:

Let $λ\in \mathbb{Q}\setminus \{0, -1\}$ and $l \geq 2$. Denote by $C_{l,λ}$ the nonsingular projective algebraic curve over $\mathbb{Q}$ with affine equation given by $$y^l=(x-1)(x^2+λ).$$ In this paper we give a relation between the number of points on $C_{l, λ}$ over a finite field and Gaussian hypergeometric series. We also give an alternate proof of a result of McCarthy (2010). We find some special values of ${_{3}}F_2$ and ${_{2}}F_1$ Gaussian hypergeometric series. Finally we evaluate the value of ${_{3}}F_2(4)$ which extends a result of Ono (1998).
