关于超椭圆族的Mahler测度

On the Mahler measure of hyperelliptic families

Marie José Bertin, Wadim Zudilin

摘要:

我们证明博伊德的“意想不到的巧合”的马勒措施的两个家庭的二元多项式定义曲线的亏格2。我们进一步等同于相同的措施,以马勒措施的多项式$y^3-y+x^3-x+kxy$的零轨迹定义椭圆曲线$k\ne0,\pm3$。

英文摘要:

We prove Boyd's "unexpected coincidence" of the Mahler measures for two families of two-variate polynomials defining curves of genus 2. We further equate the same measures to the Mahler measures of polynomials $y^3-y+x^3-x+kxy$ whose zero loci define elliptic curves for $k\ne0,\pm3$.
