This webpage is devoted to my academic activities. The main aim is to provide basic information about me and to share sources with scientific content.
About me
My name is František Štampach and currently I am an Assistant Professor at Department of Applied Mathematics of the Faculty of Information Technology at Czech Technical University in Prague, and member of MAFIA group.


Research Interests: Spectral analysis of linear operators (Jacobi, Hankel, Toeplitz, Schrödinger, etc.), mathematical methods in quantum physics, orthogonal polynomials, special functions, moment problem, continued fractions, analytic number theory, nonselfadjoint operators.
My Curiculum Vitae and my Doctoral Thesis.
