Abstract:

The notion of $L^1$-variation and the space $L^1BV$ arise in the study of regularity properties of solutions to perturbed conservation laws. In this article we show that this notion is equivalent to variation in the regular sense, and therefore the space $L^1BV$ is the same as the space $BV$ in the sense of Cesari-Tonelli. We also point out some connection between the space $L^1BV$ and the Favard classes for translation semigroups.

Keywords:$L^1$-variation  variation  total variation  essential variation  conservation laws  perturbed conservation laws  $m$-dissipative operator  invariant set  Favard class
