Approximation of convex functions in Asplund generated spaces
An Asplund generated space is a Banach wihich contains densely the linear image of an Asplund space. We prove that every continuous convex function on an Asplund generated space can be represented...

Traces of Orlicz-Sobolev functions under general growth restrictions
We prove an estimate for the trace operator in spaces whose weak derivatives are in Orlicz spaces without constraints upon the growth of the generating Young function. This extends the known trace theorems establis...
