Abstract

The powers of generating functions and its properties are analyzed. A new class of functions is introduced, based on the application of compositions of an integer nn, called composita. The methods for obtaining reciprocal and reverse generating functions, and solutions of the functional equations F(A(x))=G(x)F(A(x))=G(x), where A(x)A(x) is an unknown generating function, are proposed. Key words: generating functions, reverse, reciprocal, composita, method.
