Families of Bianchi modular symbols: critical base-change p-adic L-functions and p-adic Artin formalism

Daniel Barrera Salazar, Chris Williams, Carl Wang-Erickson

Let $K$ be an imaginary quadratic field. In this article, we study the eigenvariety for ${\mathrm{GL}}_2/K$, proving an étaleness result for the weight map at non-critical classical…
