A Korovkin type approximation theorems via -convergence
Oktay Duman (2007)
Czechoslovak Mathematical Journal
Using the concept of -convergence we provide a Korovkin type approximation theorem by means of positive linear operators defined on an appropriate weighted space given with any interval of the real line. We also study rates of convergence by means of the modulus of continuity and the elements of the Lipschitz class.

A new proof of multisummability of formal solutions of non linear meromorphic differential equations
Jean-Pierre Ramis, Yasutaka Sibuya (1994)
Annales de l'institut Fourier
We give a new proof of multisummability of formal power series solutions of a non linear meromorphic differential equation. We use the recent Malgrange-Ramis definition of multisummability. The first proof of the main result is due to B. Braaksma. Our method of proof is very different: Braaksma used Écalle definition of multisummability and Laplace transform. Starting from a preliminary normal form of the differential equationthe idea of our proof is to interpret a formal power series solution...
