V. Hanf traditionally, are regarded as quite far apart. One of them is the the theory of elliptic equations and boundary value problems—in particular, the theory of singular integral equations. The other is topology and algebraic geometry, where very specific elliptic operators have been considered. A sign

O. Bauer,S. Al-Hasani,K. Diedrichk Vishik was one of the prominent figures in the theory of partial differential equations. His ground-breaking contributions were instrumental in integrating the methods of functional analysis into this theory..The book is based on the memoirs of his friends and students, as well as on the recollect
