To give the postgraduate student a solid knowledge about the basic concepts of functional analysis, and about some of its applicatons. Such knowledge is important for research in mathematical analysis, and for research within some other fields of mathematical character such as control theory.

Judgement and Approach
For a passing grade the doctoral student must be able to identify situations in which the methods of functional analysis apply, for example in other mathematical fields such as ordinary and partial differential equations, function spaces and operator theory.
The course treats fundamental properties of Banach and Hilbert spaces and the bounded linear operators defined on them: • Banach spaces, the Hahn-Banach Theorem, weak convergence and weak precompactness of the unit ball. • Hilbert spaces. Examples including L^2 spaces. Orthogonality, orthogonal complement, closed subspaces, the Projection Theorem. The Riesz Representation Theorem. • Orthonormal sets, Bessel's Inequality. Complete orthonormal sets, Parseval's Identity. • The Baire Category Theorem and its consequences for operators on Banach spaces (the Uniform Boundedness, Open Mapping, Inverse Mapping and Closed Graph theorems). Strong convergence of sequences of operators. *Bounded and compact linear operators on Banach spaces and their spectra. *The Spectral Theorem for compact self-adjoint operators on Hilbert spaces.
