Functions with ultradifferentiable powers

Vincent Thilliez

We study the regularity of smooth functions $f$ defined on an open set of $R^{n}$ and such that, for certain integers $p \geq 2$ , the powers $f^{p} : x \mapsto (f (x))^{p}$ belong t…

Estimates for Weierstrass division in ultradifferentiable classes

Vincent Thilliez

We study the Weierstrass division theorem for function germs in strongly non-quasianalytic Denjoy-Carleman classes $C_{M}$ . For suitable divisors $P(x,t)=x^d+a_1(t)x^{d-1}+…

Łojasiewicz ideals in Denjoy-Carleman classes

Vincent Thilliez

The classical notion of Łojasiewicz ideals of smooth functions is studied in the context of non-quasianalytic Denjoy-Carleman classes. In the case of principal ideals, we obtain a…

On the non-extendability of quasianalytic germs

Vincent Thilliez

Let $E_{1} (M)^{+}$ be the local ring of germs at 0 of functions belonging to a given Denjoy-Carleman quasianalytic class in a neighborhood of 0 in $[0, + \infty [$ . We show that…

Smooth solutions of quasianalytic or ultraholomorphic equations

Vincent Thilliez

In the first part of this work, we consider a polynomial $ϕ (x, y) = y^{d} + a_{1} (x) y^{d - 1} + ... + a_{d} (x)$ whose coefficients $a_{j}$ belong to a Denjoy-Carleman quasianalytic local ring $ \…

Division by Flat Ultradifferentiable Functions and Sectorial Extensions

Vincent Thilliez

We consider classes $A_{M} (S)$ of functions holomorphic in an open plane sector $S$ and belonging to a strongly non-quasianalytic class on the closure of $S$ . In $ \m…
