摘要
本文绘出了完全椭圆积分K(γ)与E(γ)的组合p(γ)E(γ)+q(γ)K(γ)(其中p(γ)、q(γ)为(0,1)上的可微函数)立单调性和凹凸性的一种判别准则,揭示了K(γ)和E(γ)的一些新性质(包括函数不等式)。利用这些性质,本文解决了关于椭圆积分的两个猜测。
In this paper,a kind of criteria of monotonicity,concavity and convecity for a class of combinations of complete elliptic integrals K (r) and E (r) are presented, and some new properties,including sharp functional inequalities,are obtained for some functions defined in terms of K (r) and E(r),by which two conjectures on K (r)and E(r) are solved.
