here is to introduce Yosida approximations for this class of equations and to show the convergence of the mild solutions of … the Yosida approximating systems in the pth-mean (p≥2) to the mild solutions of such equations. Moreover, in the special … case when the neutral term has no delay, the weak convergence of probability measures induced by the mild solutions of the …
