Hochschild cohomology of algebras arising from categories and from bounded quivers
(European Mathematical Society, 2019-10)
The main objective of this paper is to provide a theory for computing the Hochschild cohomology of algebras arising from a linear category with finitely many objects and zero compositions. For this purpose, we consider ...
Cyclic homology, tight crossed products, and small stabilizations
(European Mathematical Society, 2014-12)
In [1] we associated an algebra 1.A/ to every bornological algebra A and an ideal IS.A/ C 1.A/ to every symmetric ideal S C `1. We showed that IS.A/ has K-theoretical properties which are similar to those of the usual ...
Fermionic origin of dark energy in the inflationary universe from unified spinor fields
(IOP Publishing, 2020-02)
In this work we explore the boundary conditions in the Einstein-Hilbert action, by considering a displacement from the Riemannian manifold to an extended one. The latter is characterized by including spinor fields into the ...
