Remarks on vector-valued Gagliardo and Poincaré–Sobolev-type inequalities with weights
-
Javier Martínez Perales
Abstract
In this paper, we review certain extensions of the Gagliardo and Poincaré- Sobolev-type inequalities to later explore the possibility of extending them to the vectorvalued setting. We restrict ourselves to the most classical case of ℓq-valued functions, where already some difficulties arise, due to the lack of a vector-valued variant of the truncation method, both on the classical and the fractional case. We think that these difficulties may be overcome in the future, and we pose some conjectures in this direction.
