Abstract:
In this article theorems are established on imbedding and compactness for spaces of functions which are $p$th power summable with weight $\nu$ over the region $\Omega\subset\mathbf R^n$ and whose $m$th derivatives are $p$-summable with weight $\mu$ over $\Omega$. Moreover, necessary and sufficient conditions for the boundedness and compactness of the imbedding operator are obtained in terms of properties of the weight functions. The case of functions vanishing on the boundary is also considered. This article represents a continuation of previous research of the authors.
