  We prove the holomorphic linearizability of germs of biholomorphisms of (C n
, 0), fixing the origin, point at which the linear part has nontrivial Jordan
blocks under the following assumptions : We first assume the eigenvalues are of
modulus less or equal than 1, and that they are non-resonant. We also assume
that they satisfied not only a classical Diophantine condition but also new
Diophantine-like conditions related to quasi-resonance phenomena.
