Local approximation of arbitrary functions by solutions of nonlocal equations

Analysis of PDEs 2017-05-24 v4

Abstract

We show that any function can be locally approximated by solutions of prescribed linear equations of nonlocal type. In particular, we show that every function is locally ss-caloric, up to a small error. The case of non-elliptic and non-parabolic operators is taken into account as well.
