Composition operator into the space of function of bounded variation

Abstract

Let Ω1,Ω2Rn\Omega_1, \Omega_2\subset \mathbb R^n and 1p<1\leq p <\infty. We study the optimal conditions on a homeomorphism f:Ω1f:\Omega_1 onto Ω2\Omega_2 which guarantee that the composition ufu\circ f belongs to the space BV(Ω1)BV(\Omega_1) for every uW1,p(Ω2)u\in W^{1,p}(\Omega_2). We show that the sufficient and necessary condition is an existence of a function K(y)Lp(Ω2)K(y)\in L^{p'}(\Omega_2) such that Df(f1(A))AK(y)dy|Df|(f^{-1}(A))\leq \int_A K(y)\,dy for all Borel sets AA.
