Abstract
There is a series of papers devoted to the construction and investigation of local polynomial models of real submanifolds of complex space (see, e.g., [1]). Among the main properties of model surfaces, we can mention the following fact. The dimension of the local group of holomorphic symmetries of a germ does not exceed the dimension of the similar group for the tangent model surface of the germ. In the present note, this assertion is presented in a much stronger form. A faithful representation of the Lie algebra of infinitesimal automorphisms of a germ in the Lie algebra of the tangent model surface is constructed.
