Students learn the fundamentals of linear spaces, particularly infinite-dimensional vector spaces, normed linear spaces, inner product spaces, and their completeness. In particular, students will become familiar with Banach and Hilbert spaces, such as sequence and function spaces, as well as linear operators acting on such spaces. The course provides students with a general understanding of the fundamental theorems of functional analysis, their important consequences, and useful applications, covering topics in operator and spectral theory. Functional analytic methods and operator and spectral theoretic tools are widely used in different areas of scientific research.
