# CEAFEL Seminar

On Friday, 14/07/2017, 15:00 — 16:00, in Room P4.35 of Mathematics Building of the IST will take place a seminar by
Yuri Karlovich (Universidad Autónoma del Estado de Morelos, Cuernavaca, México) with title

“Algebras of convolution type operators with PSO data”

The Fredholm symbol calculus is constructed for the Banach algebras generated on the weighted Lebesgue spaces with slowly oscillating Muckenhoupt weights by all multiplication operators by piecewise slowly oscillating functions and by all convolution operators with piecewise slowly oscillating presymbols being Fourier multipliers. A new approach of identifying local spectra is presented, which allows one to complete the description of the Fredholm symbol calculus.
