For every negative fundamental discriminant $-f$ and every $k\geq1$, we construct a rational function $R_{f,2k}\in\mathbb{Q}(x_1,\ldots,x_{2k})$ and a constant $r_{f,2k}\in\mathbb{Q}^\times$ such that \[ m(R_{f,2k})=r_{f,2k}L'(\chi_{-f},1-2k), \] where $m$ denotes the logarithmic Mahler measure and $\chi_{-f}$ is the q...
For an odd prime $p$, let $A_j$ be the $\omega^j$-eigenspace of the $p$-primary class group of $\mathbb Q(\zeta_p)$. Fix an even integer $d\ge4$, put $N=(p-1)/d$, and let $U_d=(\mathbb Z/d\mathbb Z)^\times$. For a relative density-one set of primes $p\equiv d+1\pmod{2d}$, we prove that the odd block $\bigoplus_{a\in U_...
Let $-f<0$ be a fundamental discriminant, $w$ the number of roots of unity in $\mathbb{Q}(\sqrt{-f})$, and $\chi_{-f}$ the associated quadratic character. We prove that there is a polynomial $R_f\in\mathbb{Q}[x,y]$ such that $m(R_f)=4wL'(\chi_{-f},-1)$. Hence the weak two-variable Chinburg conjecture holds.
