Sharp Hardy inequalities for Sobolev-Bregman forms
Michał Kijaczko, Julia Lenczewska
We obtain sharp fractional Hardy inequalities for the half-space and for convex domains. We extend the results of Bogdan and Dyda and of Loss and Sloane to the setting of Sobolev-B…

On density of compactly supported smooth functions in fractional Sobolev spaces
Bartłomiej Dyda, Michał Kijaczko
We describe some sufficient conditions, under which smooth and compactly supported functions are or are not dense in the fractional Sobolev space for an open, bounded…
