Goodman's conjecture on the coefficients of multivalent functions was proposed in complex analysis in 1948 by Adolph Winkler Goodman, an American mathematician.

Formulation

Let be a -valent function. The conjecture claims the following coefficients hold:

Partial results

It's known that when , the conjecture is true for functions of the form where is a polynomial and is univalent.
