Abstract
In this paper, we study some important basic properties of Dunkl-bounded variation functions. In particular, we derive a way of approximating Dunkl-bounded variation functions by smooth functions and establish a version of the Gauss–Green Theorem. We also establish the Dunkl BV capacity and investigate some measure theoretic properties, moreover, we show that the Dunkl BV capacity and the Hausdorff measure of codimension one have the same null sets. Finally, we develop the characterization of a heat semigroup of the Dunkl-bounded variation space, thereby giving its relation to the functions of Dunkl-bounded variation.

Summary
Dunkl operator is found to play an increasingly important role in the study of many special functional problems with reflective symmetry. Dunkl operator is a parameterized differential difference operator related to the finite reflection group, which operates in the Euclidean space In recent years, these operators and their generalizations have gained considerable interest in various fields of mathematics and physics.
