Abstract: In this paper, we establish some new spectral properties of bounded operators acting in Banach spaces by means of the concept of quasi-compact operators. Furthermore, we discuss the incidence of some perturbation results on the… read more here.

Abstract: We define the quasi-compact Higgs $G^{\mathbb C}$-bundles over singular curves introduced in our previous paper for the Lie group SL($N$). The quasi-compact structure means that the automorphism groups of the bundles are reduced to the… read more here.
