Kolloquium Wilhelm Killing: Dr. José Luis Romero (Wien): Sampling and time-frequency analysis
Thursday, 12.12.2019 16:30 im Raum M5
The sampling problem concerns the reconstruction of a function from
samples (point evaluations) taken on a certain subset. The most
classical results, due to Shannon and Beurling, involve bandlimited
functions (that is, functions whose Fourier transform is supported on
the unit interval) and provide a precise geometric characterization of
all configurations of points that lead to reconstruction. I will
present modern variants of these results and their implications in
other fields, notably in the construction of functional expansions
consisting of time-frequency shifts of a given profile function (known
as Gabor or Weyl-Heisenberg systems).
