On Timelike Tubular Weingarten Surfaces in Minkowski 3-Space

Abstract

In this paper, we study the timelike tubular Weingarten surfaces in 3-dimensional Minkowski space $I{R}_1^3$.We have obtained some conditions for being $(K_{II},H)$, $(K_{II},K)$, timelike tubular Weingarten surfaces where are the second Gaussian curvature the Gaussian curvature and the mean curvature, respectively.
