We prove uniform Ancona—Gouëzel—Lalley inequalities for an extension by a hyperbolic group G of Markov map which allows to deduce that the visual boundary and Martin are Hölder equivalent. As application, we identify set minimal δ-conformal measures regular cover convex-cocompact CAT(-1)-manifold with covering group, provided this is hyperbolic. In setting, uniformity minimal, densities in sens...

In this paper we first construct the non-split extension $overline{G}= 2^{6} {^{cdot}}Sp(6,2)$ as a permutation group acting on 128 points. We then determine the conjugacy classes using the coset analysis technique, inertia factor groups and Fischer matrices, which are required for the computations of the character table of $overline{G}$ by means of Clifford-Fischer Theory. There are two inerti...
