# Research

Currently, during my doctoral studies, my focus is on generalized smooth functions (GSF) theory which is a branch of Colombeau theory where generalized functions share a number of fundamental properties with smooth functions, in particular with respect to composition and nonlinear operations. At the present, I am studying generalized holomorphic functions under the supervision of Dr. Paolo Giordano, Privatdoz.
