Joint spectra of the tensor product representation of the direct sum of two solvable Lie algebras
Enrico Boasso
Given two complex Banach spaces and , a tensor product of and in the sense of [14], two complex solvable finite dimensional Lie alge…
The -inverse in rings and in the Banach context
Enrico Boasso, Gabriel Kantun-Montiel
In this article the -inverse will be studied. Several equivalent conditions for the existence of the -inverse in rings will be given. In particular, the conditions e…

On the joint spectral radius of a nilpotent Lie algebra of matrices
Enrico Boasso
For a complex nilpotent finite dimensional Lie algebra of matrices,and a Jordan-Hölder basis of it, we prove a spectral radius formula which extends a well-known result for commuti…
Joint spectrum for quasi-solvable Lie algebras of operators
Enrico Boasso
Given a complex Banach space and a joint spectrum for complex solvable finite dimensional Lie algebras of operators defined on , we extend this joint spectrum to quasi-solva…
