Deformations de reseaux dans certains groupes resolubles

摘要

We aim to study local rigidity and deformations for the following class of groups: the semidirect product Γ = Z~n ×_A Z where n ≥ 2 is an integer and A is a hyperbolic matrix in SL(n, Z), considered first as a lattice in the solvable Lie group G = R~n ×_A
