“…The purpose of this work is to study the class of abstract stochastic evolution equations obtained by accounting for more general nonlinear perturbations (in the sense of McKean-Vlasov equations, as described in [19]) in the mathematical description of phenomena involving an fBm. In particular, the existence and convergence results we present constitute generalizations of the theory governing standard models arising in the mathematical modeling of nonlinear diffusion processes [1,[16][17][18][19]22], communication networks [4], Sobolev-type equations arising in the study of consolidation of clay [8], shear in second-order fluids [23], and fluid flow through fissured rocks [24]. As a part of our general discussion, we establish an approximation result concerning the effect of the dependence of the nonlinearity on the probability law of the state process, as well as the noise arising from the stochastic integral, for a special case of (1.1) arising often in applications.…”
