Extension operators for spaces of infinitely differentiable functions
(Bilkent University, 2005)
We start with a review of known linear continuous extension operators for the spaces of Whitney functions. The most general approach belongs to PawÃlucki and Ple´sniak. Their operator is continuous provided that the ...
Extension problem and bases for spaces of infinitely differentiable functions
(Bilkent University, 2017-04)
We examine the Mityagin problem: how to characterize the extension property in geometric terms. We start with three methods of extension for the spaces of Whitney functions. One of the methods was suggested by B. S. Mityagin: ...
