© 2019, Foundation for Scientific Research and Technological Innovation.We study timelike surface, curve pairs by using their curvature properties. We assume that timelike surfaces whose one of the principal curvatures is identically constant, have diagonalizable shape operators in E13. Then we give some results about timelike surfaces on which inclined curves lie as geodesic curves.
