Abstract: In the 1920's J. F. Ritt studied possible ways of writing a polynomial with complex coefficients as a functional composition of polynomials of lower degree. Polynomials of degree greater than 1 which cannot be written as a composition of polynomials which have strictly lower degree are said to be indecomposable. By induction, one may write any polynomial of degree greater than 1 as a composition of indecomposables; such a decomposition is said to be complete. Complete decomposition does not need to be unique, but Ritt proved that the number of polynomials in a complete decomposition is unique, as well as the sequence of degrees of these polynomials. Several authors followed ideas of Ritt to determine new decomposition invariants and to extend existing results to wider classes of polynomials. In this talk I will give an overview of known results and present some recent contributions. [hide abstract] | |
