Abstract
In this paper, we introduce a theory of convolution-type (fractional) derivatives in the algebra of Colombeau generalized stochastic processes. Non-regularized and regularized Caputo fractional derivatives of Colombeau generalized stochastic processes are introduced and some of their properties are studied. As an example, a certain stochastic Cauchy problem is considered in two cases, with nonregularized and regularized Caputo fractional derivatives.
