Title: Spectral Theory of Unbounded Block Operator Matrices and Applications

Abstract: Block operator matrices are matrices the entries of which are linear operators between Banach or Hilbert spaces. They arise in various areas of mathematics and mechanics, and they are paid considerable attention for their theoretical research value and practical applications. In this talk, we will introduce the definition of spectrum of block operator matrix and illustrate some examples of applications.  In the end, some basic research methods of block operator matrices are introduced to characterize the spectral properties.
