In this talk, we discuss the analogy between pro C*-algebra and C*-algebra. Also, we discuss that any pro C* algebra arises as the projective limit of C*-algebras (hence, the name). With this observation, we write the spectrum of a pro C*-algebra and see how it differs from its C*-algebra counterpart. We will also see necessary and sufficient conditions under which a pro C*-algebra isomorphic to a C*-algebra.

Abstract: In the talk I will present the open questions and state of the art on Hilbert schemes of points, focusing on the most accessible questions. In one sentence: the Hilbert scheme parameterizes deformations of finite rank algebras, which accounts for its usefulness, while it is highly singular which accounts for the difficulties, jointly these features make its investigation a very active area.
