Reflexive and dihedral (co)homology of a pre-additive category

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2001
The group dihedral homology of an algebra over a field with characteristic zero was introduced by Tsygan (1983). The dihedral homology and cohomology of an algebra with involution over commutative ring with identity, associated with the small category ...

On Marginal Automorphisms of Free Nilpotent Lie Algebras

open access: yesJournal of Mathematics, 2020
Let L be the free nilpotent Lie algebra of finite rank over a field of characteristic zero. We define the concepts of marginal ideals and marginal automorphisms of L, and we give some results on marginal automorphisms.

Zero Triple Product Determined Matrix Algebras

open access: yesJournal of Applied Mathematics, 2012
Let A be an algebra over a commutative unital ring C. We say that A is zero triple product determined if for every C-module X and every trilinear map {⋅,⋅,⋅}, the following holds: if {x,y,z}=0 whenever xyz=0, then there exists a C-linear operator T:A3⟶X ...

Noncommutative version of Borcherds' approach to quantum field theory

open access: yes, 2014
Richard Borcherds proposed an elegant geometric version of renormalized perturbative quantum field theory in curved spacetimes, where Lagrangians are sections of a Hopf algebra bundle over a smooth manifold.

Loop Quantum Gravity Vacuum with Nondegenerate Geometry

open access: yesSymmetry, Integrability and Geometry: Methods and Applications, 2012
In loop quantum gravity, states of the gravitational field turn out to be excitations over a vacuum state that is sharply peaked on a degenerate spatial geometry.
