Harmonic and polyanalytic functional calculi on the $S$ -spectrum for unbounded operators

Fabrizio Colombo, Antonino De Martino, Stefano Pinton

Harmonic and polyanalytic functional calculi have been recently defined for bounded commuting operators. Their definitions are based on the Cauchy formula of slice hyperholomorphic…

The fine structure of the spectral theory on the $S$ -spectrum in dimension five

Fabrizio Colombo, Antonino De Martino, Stefano Pinton +1

Holomorphic functions play a crucial role in operator theory and the Cauchy formula is a very important tool to define functions of operators. The Fueter-Sce-Qian extension theorem…
