We introduce the notion of joint torsion for several commuting operators satisfying a Fredholm condition. This new secondary invariant takes values in the group of invertibles of a field. It is const...
We extend the holomorphic analytic torsion classes of Bismut and K\"ohler to arbitrary projective morphisms between smooth algebraic complex varieties. To this end, we propose an axiomatic definition...
This article introduces the concept of a t-supplemented module as follows: Given a hereditary torsion theory in Mod R with associated torsion functor t, we say that a module M is t-supplemented when f...
