Alexander Ulanovskii

Professor Alexander Ulanovskii is a faculty member at the University of Stavanger's Faculty of Science and Technology, Department of Mathematics and Physics. His research focuses on harmonic analysis, functional analysis, and sampling theory, with contributions to signal processing, Fourier analysis, and mathematical physics. He has collaborated extensively with scholars like Olevskii and Zlotnikov, publishing in high-impact journals such as Journal of Functional Analysis and Mathematische Annalen.

Research interests include the geometry of functional spaces (e.g., Paley-Wiener spaces), uniqueness properties of convolutions, and applications of sampling theory to signal reconstruction. Recent work explores quasi shift-invariant spaces and Gabor frames, addressing theoretical challenges in exponential systems and spectral gaps.

His publications span over two decades, addressing topics such as discrete translates in function spaces, irregular sampling in Bernstein spaces, and interpolation theorems. Notable contributions include extensions of the Titchmarsh convolution theorem and studies on Fourier quasicrystals.

No specific awards or grants are explicitly listed in the text, though his prolific publication record reflects sustained academic impact. Advising and team collaborations are evident through co-authorship networks but lack detailed descriptions of student mentoring or lab affiliations.
