本文研究区间内阿贝尔积分∮ γ i (h) y d x 和∮ γ i (h) x y d x 之比的单调性,其中 i= 1, 2,且 γ i (h) 是某些亏格 2 的超椭圆曲线的紧分量,h∈ γ i (h)。我们对Wang et al.(2014)[18]提出的两个猜想给出了肯定的答案。
In this paper, we study the monotonicity of the ratio of the Abelian integrals,∮ γ i (h) y d x and∮ γ i (h) x y d x, in an interval, where i= 1, 2, and γ i (h) is a compact component of some hyperelliptic curves with genus 2 as h∈ γ i (h). We give positive answers to the two conjectures proposed by Wang et al.(2014)[18].
