Topologizability and Related Properties of the Iterates of Composition Operators in Gelfand-Shilov Classes [PDF]

[EN] We analyse the behaviour of the iterates of composition operators defined by polynomials acting on global classes of ultradifferentiable functions of Beurling type which are invariant under the Fourier transform.

A parametrised version of Moser's modifying terms theorem [PDF]

A sharpened version of Moser's `modifying terms' KAM theorem is derived, and it is shown how this theorem can be used to investigate the persistence of invariant tori in general situations, including those where some of the Floquet exponents of the ...

Polynomials on the space of ω-ultradifferentiable functions

Opuscula Mathematica, 2007
The space of polynomials on the the space \(D_{\omega}\) of \(\omega\)-ultradifferentiable functions is represented as the direct sum of completions of symmetric tensor powers of \(D^{\prime}_{\omega}\).

Regularity of functions: Genericity and multifractal analysis [PDF]

, 2014
As surprising as it may seem, there exist functions of C∞(R) which are nowhere analytic. When such an unexpected object is found, a natural question is to ask whether many similar ones may exist. A classical technique is to use the Baire category theorem
