|The Dyadic Harmonic
Analysis Group was established in 1995 by István Blahota, György
Gát, Károly Nagy and Rodolfo Toledo. The leader of the research
group was György Gát in the period 1995-2015. In 2014 Erik Bajalinov
joined to the research group.
Dyadic Harmonic analysis is a wellknown area of the mathematics in Hungary. We are interested in approximation theory with respect to the Walsh system, its rearrangements (Walsh-Kaczmarz system) and its generalizations. Our research team investigates Fourier series, Fejér means, dyadic derivate, dyadic integral, Sunuouchi operators, Marcinkiewicz means and logarithmic means on bounded Vilenkin groups, on unbounded Vilenkin groups and on noncommutative groups (CTD).
Recently, Walsh-Fourier series are used to develop numerical methods for the approximation of differential equations and the analysis of seasonal time series.
|The members of the group have some lectures on International Conference related to approximation theory.
