Konvexita v normovaných lineárních prostorech a v obecnějších prostorech

open access: yes, 2018
We study questions concerning convexity and the existence of the nearest point for a given set in spaces equipped with either a norm, or with a more gen- eral functional, namely a quasinorm or an α−norm. We characterize convexity in a Hilbert space.

Maximal noncompactness of limiting Sobolev embeddings

open access: yes
We develop a new method suitable for establishing lower bounds on the ball measure of noncompactness of operators acting between considerably general quasinormed function spaces.
