On improved fractional Sobolev-Poincaré inequalities

Bartłomiej Dyda, Lizaveta Ihnatsyeva, Antti V. Vähäkangas

We prove a certain improved fractional Sobolev-Poincaré inequality on John domains; the proof is based on the equivalence of the corresponding weak and strong type inequalities. We…

Conditions for building a community of practice in an advanced physics laboratory

Paul W. Irving, Eleanor C. Sayre

In this paper we explore the theory of communities of practice in the context of a physics college course and in particular the classroom environment of an advanced laboratory. We…
