Abstract:

In this report, we demonstrate the existence of variational problems with infima that depend continuously upon the Sobolev space from which the competing functions are taken. It is shown, for each $\alpha$ in a particular class of continuous functions, that there is a variational integral and boundary conditions such that, for every $p\in [1,\infty]$, the infimum is equal to $\alpha(p)$ if the admissible class is a subset of W1,p. So the manner in which the infimum depends upon the Sobolev exponent may be prescribed.
