B-tubular surfaces in Lorentzian Heisenberg group H3 [Superfícies B-tubulares no grupo H3 de Lorentz-Heisenberg]

Abstract

In this paper, B-tubular surfaces in terms of biharmonic spacelike new type B-slant helices according to Bishop frame in the Lorentzian Heisenberg group H3 are studied. The Necessary and sufficient conditions for new type B-slant helices to be biharmonic are obtained. B-tubular surfaces in the cLorentzian Heisenberg group H3 are characterized. Additionally, main results in Figures 1, 2, 3 and 4 are illustrated. © 2014, Eduem - Editora da Universidade Estadual de Maringa. All rights reserved.
