Abelian self-commutators in finite factors
Gabriel Nagy
An abelian self-commutator in a C*-algebra is an element that can be written as , with such that and commute. It is s…
Spectral Symmetry in II_1 Factors
Sang Hyun Kim, Gabriel Nagy
A self-adjoint element in a finite AW*-factor is spectrally symmetric, if its spectral measure under the quasitrace is invariant under the change of variables . We…
The mass of spacelike hypersurfaces in asymptotically anti-de Sitter space-times
Piotr T. Chrusciel, Gabriel Nagy
We give a Hamiltonian definition of mass for spacelike hypersurfaces in space-times with metrics which are asymptotic to the anti-de Sitter one, or to a class of generalizations th…
A note on idempotents in finite AW*-factors
Gabriel Nagy
We prove that the value of the quasi-trace on an idempotent element in a AW*-factor of type II_1 is the same as the dimension of its left (or right) support.
