Abstract

In the setting of a metric space X equipped with a doubling measure that supports a Poincaré inequality, we show that if u_i→ u strictly in BV(X), i.e. if u_i→ u in L¹(X) and \Vert Du_i\Vert(X)→\Vert Du\Vert(X), then for a subsequence (not relabeled) we have \widetildeu_i(x)→ \widetildeu(x) for \mathcal H-almost every x∈ X∖ S_u.
