Extended description for Functional Analysis: Math 5130-5131: Topics in functional analysis, at the choice of the instructor and students, including the following.

Theory of Banach spaces: duality, reflexivity, weak and weak* topologies. Hahn-Banach, Banach-Steinhaus, Banach-Alaoglu theorems. Krein-Milman theorem. Linear bounded operators on Hilbert spaces: compact, integral, trace class, Fredholm, Hilbert-Schmidt, Toepliz, Volterra. Compact self-adjoint operators with applications to the classical Sturm-Liouville theory. Spectral theory of unbounded self-adjoint and normal operators on Hilbert spaces, quadratic forms. Examples and counterexamples of self-adjoint operators, and the role of the Fourier transform. Spectral theory of differential operators with constant coefficients. Unitary and positivity preserving operator semigroups, resolvents, Trotter product formula, Hille-Yosida theorem. Other topics may include distributions, commutative Banach and C* algebras, Gelfand transform and its relation to the spectral theorem for bounded normal operators, Banach algebra L1, Kaplansky density theorem, Gelfand-Naimark-Segal construction, introduction to von Neumann algebras and non-commutative integration. Applications to probability, quantum mechanics, Kigami's resistance forms and Dirichlet forms.
