Non-local functionals, total variation, and Gamma-convergence with respect to area-strict convergence

Panu Lahti, Zhuolin Li

We study a class of non-local functionals that was introduced by Brezis--Seeger--Van Schaftingen--Yung, and can be used to characterize the total variation of functions. We establi…

Lusin approximation for functions of bounded variation

Panu Lahti, Khanh Nguyen

We prove a Lusin approximation of functions of bounded variation. If $f$ is a function of bounded variation on an open set $Ω \subset X$ , where $X = (X, d, μ)$ is a given complete doubl…
