The role of Riemann generalized derivative in the study of qualitative properties of functions

Marshal Ash [3] introduced the concept of (sigma,tau) differentiable functions and studied the Riemann generalized derivatives In this article we study the convexity and monotonicity of (sigma,tau) differentiable functions, using results by Hincin, Humke and Laczkovich, and using the Riemann gen...
