Spectral properties of compact normal quaternionic operators
Riccardo Ghiloni, Valter Moretti, Alessandro Perotti
General, especially spectral, features of compact normal operators in quaternionic Hilbert spaces are studied and some results are established which generalize well-known propertie…

Semigroups over real alternative *-algebras: generation theorems and spherical sectorial operators
Riccardo Ghiloni, Vincenzo Recupero
The aim of this paper is twofold. On one hand, generalizing some recent results obtained in the quaternionic setting, but using simpler techniques, we prove the generation theorems…
