In Grothendieck’s sheaf theoretic approach to Algebraic Geometry the concept of a ringed space is fundamental.
In my talk I will explain the role that the new notion of “C*-ringed space”, that is, a topological space equipped with a sheaf of C*-algebras, plays in the sheaf cohomology theory for C*-algebras that we develop jointly with Pere Ara (Barcelona).
