Title: Self-adjoint extensions via boundary triples
Abstract: To better understand self-adjoint extensions of symmetric operators via boundary triples (and associated topics such as Krein resolvent formula), we will consider how this theory works for matrices. The analog of a symmetric operator is a rectangular matrix. Because its domain isn't dense, its adjoint is not a matrix but must be interpreted as a linear relation. With this understanding, the rest of the theory follows. Some interesting links emerge, for example the Dirichlet-to-Neumann map is a Schur complement in the matrix case.
Student Working Seminar in Category Theory
Time: 5:00PM - 6:00PM
Location: BLOC 506A
Speaker: Zheng Kuang, Texas A&M University
Title: Riehl Ch1~Ch2.1
Abstract: This is review seminar for the basic category theory. We will deal with the notion of category, functor, categorical equivalence, natural transformation, diagram, 2-categories, and representable functors..
