Some characterications for the curvatures of ruled surfaces in non-Eucledian spaces

This study is consisted of five chapters: In the first chapter, some basic definitions and theorems of 3-dimensionel Lorentz, Galilean and pseudo-Galilean spaces are given. In chapter second, some basic definitions of ruled surfaces in 3-dimensional Lorentz, Galilean and pseudo-Galilean spaces are given. In chapter third, Lamarle Formula for the ruled surfaces in 3-dimensional Lorentz space are given. In chapter fourth, the relation between Gaussian curvature and distribution parameter of a ruled surface in 3-dimensional Galilean and pseudo-Galilean spaces are given. In chapter fifth, some examples which concerning this study are given.
