Beurling's method in the theory of quasianalytic functions
The talk is will be devoted to two questions in the theory of quasianalytic
Carleman classes. The first one is how to describe the image of a quasianalytic
Carleman class under Borel's map $f\to\{f^{(n)}(0)/n!\}_{n\geq 0}$ ?
The second one is how to sum the formal Taylor series of functions in quasianalytic Carleman classes? In the talk, I will present a method of Beurling that gives a solution to both of the problems for some quasianalytic Carleman classes. If time permits, I will also discuss the image problem in some non-quasianalytic classes.
