Abstract

We study regularity properties of the unique solution of a mean-field GG-SDE. More precisely, we consider a mean-field GG-SDE with square-integrable random initial condition and establish its first and second order Fr\'echet differentiability in the random initial condition and specify the GG-SDEs of the respective Fr\'echet derivatives.
