  • understand various types of convergence and how to verify them
  • master basic operations in Hilbert spaces
  • understand the role of linear algebra in analysis
  • know the role of $L^2$ and perform basic operations herein
  • master the basic manipulations with Fourier transform
  • know when one should apply Fourier series or the Fourier transform
  • expand square-integrable functions in various bases
  • master basic wavelet theory
  • perform calculations with the L^p-spaces and the corresponding sequence spaces

Course Content

Normed vector spaces, Hilbert spaces, bases in Hilbert spaces, basic operator theory, the spaces L^p and l^p, approximation, the Fourier transform, convolution, the sampling theorem, Sturm-Liouville theory and special basis functions (e.g, Legendre and Hermite polynomials), an introduction to wavelet theory.
