The harmonic evolute of a surface in Minkowski 3-space

Željka Milin Šipuš, Vladimir Volenec

Abstract


In this paper we describe harmonic evolutes of surfaces in Minkowski 3-space. In particular, we study properties of harmonic evolutes of constant mean curvature surfaces and their relation to parallel surfaces. Furthermore, we study harmonic evolutes of surfaces of revolution.

Keywords


harmonic evolute; focal set; parallel surface; Minkowski 3-space
