 In this talk, we will say how to obtain a higher differentiation using fat point as Severa's idea and how to further obtain Van Est using a suitable Eilenberg-Mac Lane space and path objects. The connection to the recent preprint of Carbera-de Hoyo will be given. Based on joint work with D. Li, L. Ryvkin, A. Wessel,  and the thesis of F. Dorsch.
