Yali Chen,Zhenxi Gong,Qiyan XingWe will focus on the function spaces introduced in the period 1935-1938 by Sobolev , and which have since played an absolutely central role in the study of partial differential equations.

Topological Vector SpacesIn 1850,Weierstrass gave the first precise (“epsilon-delta”) definition of the concept of the limit of a function at a point. He used the notion of arbitrarily small numbers and the notation lim introduced by L’Huilier and used by Cauchy in his Analysis course.
