Let $K/k$ be an extension of number fields and $H_k$, $H_K$ their respective Hilbert class fields. Is there a transfer map from $\text{Gal}(H_k/k)$ to $\text{Gal}(H_K/K)$?

Let $\mathcal E(f,g)$ be a dirichlet form on a metric measure space $(X, d, \mu)$ where $\mu$ is a finite (or probability) Borel measure. We say that $J$ is the jump kernel of $\mathcal E(f,g)$ if $$ \mathcal E(f,g) = \iint ((f(x) - f(y)) (g(x) - g(y...

In addition to basic theory of abelian varieties, etále cohomology, elliptic curves, and what’s described in his latest report, what else do I must know prior to reading his preprints? His work involves use of some recent ideas arise from $p$-adic hodge...

$\mathrm{k}$-$\operatorname{opt}$ moves are an idea to improve non-optimal Hamilton cycles in weighted symmetric graphs by exchanging $\mathrm{k}$ tour-edges with $\mathrm{k}$ edges that do not belong to the tour, have smaller weightsum and yield a different...
