Strict s-numbers of non-compact Sobolev embeddings into continuous functions
Jan Lang, Vít Musil
For limiting non-compact Sobolev embeddings into continuous functions we study behavior of Approximation, Gelfand, Kolmogorov, Bernstein and Isomorphism s-numbers. In the one dimen…
Optimal domain spaces in Orlicz-Sobolev embeddings
Andrea Cianchi, Vít Musil
We deal with Orlicz-Sobolev embeddings in open subsets of . A necessary and sufficient condition is established for the existence of an optimal, i.e. largest possible…
Strict s-numbers of the Volterra operator
Özlem Bakşi, Taqseer Khan, Jan Lang +1
For Volterra operator and summation operator , we obtain exact values of Approximation, Gelfand, Kolmogorov, Mityagin and Isomor…
Interpolation theorem for Marcinkiewicz spaces with applications to Lorentz gamma spaces
Vít Musil, Rastislav Oľhava
This paper is devoted to the interpolation principle between spaces of weak type. We characterise interpolation spaces between two Marcinkiewicz spaces in terms of Hardy type opera…
