Dual surfaces defined by z = f(u) + g(v) in simply isotropic 3-space I(double-struck) 3 1

Abstract

In this study, we define the dual surfaces by z = f(u) + g(v) and also classify these surfaces in I(double-struck) 3 1 satisfying some algebraic equations in terms of the coordinate functions and the Laplace operators according to fundamental forms of the
