On essential $\varphi$-variation
J. Ewert, S. P. Ponomarev Institute of Mathematics, Pomeranian Pedagogical Academy
Abstract:
We study relations between the classical essential variation and approximate continuity. In particular, we show that the classical essential variation of functions on the so-called $\tau_D$-regular sets agrees with essential variation in the sense of W. P. Ziemer.
Keywords:
$\varphi$-variation, essential $\varphi$-variation, metric space, approximate continuity.
