Invertibility in a C*-algebra of operators acting on the Hardy space of the unit disc via tensor products
Uğur Gül
Hacettepe Üniversitesi, Turkey
Özet : In this talk we will deal with invertibility of certain linear algebraic sums in a C*-algebra generated by Toeplitz operators and Fourier multipliers which act on the Hardy space of the unit disc. Finding an invertibility criterion we will apply this criterion to the characterization of Fredholmness for some elements in a tensor product algebra which act on the Hardy space of the bi-disc. These results constitute joint work with B.B.Koca of İstanbul University
