The goal of the talk is to discuss some recent results

(obtained in

joint work with Bernhard Lamel) concerning the structure of the

local and

global groups of CR automorphisms of real-analytic CR manifolds,

whose

levi-form is allowed to degenerate. We will mainly focus on the

class of

real-analytic hypersurfaces containing no holomorphic curves and

show that in

such a setting the local automorphism groups can be analytically

parametrized

by a finite jet at any given point.
