Abstract:
The Wiman–Valiron theory is more than one hundred years old. It enables one to estimate the growth of derviatives of an entire function $f(z)$ at the point $z_0$ of the circle $z=R$ where $f(z)$ attains its maximum value on this cicrle, in terms of $f(z_0)$ and quantities equivalent to the order and type of $f$. The talk is about various ways of generalization of this theory for functions of several complex variables and applications to two problems: the proof of absence of nonconstant entire solutions of the Korteweg–de Vries equation and a description of solutions of complexity one for the heat equation.
