Generic local deformation rings when $l \neq p$

Abstract

We determine the local deformation rings of sufficiently generic mod ll representations of the Galois group of a pp-adic field, when lpl \neq p, relating them to the space of qq-power-stable semisimple conjugacy classes in the dual group. As a consequence we give a local proof of the lpl \neq p Breuil--M\'{e}zard conjecture of the author, in the tame case.
