An equivalent definition for multiplicities of a quaternionic eigenvalue

Stefano Spessato

In this paper we introduce two definitions for algebraic and geometric multiplicities of a quaternion right eigenvalue. This definitions are equivalent to the classical ones. Howev…

$L^{2}$ -cohomology and quasi-isometries on the ends of unbounded geometry

Stefano Spessato

In this paper we study the minimal and maximal $L^{2}$ -cohomology of oriented, possibly not complete, Riemannian manifolds. Our focus will be on both the reduced and the unreduced…
