Noncommutative de Sitter and FRW spaces
Maja Buric, John Madore
Several versions of fuzzy four-dimensional de Sitter space are constructed using the noncommutative frame formalism. Although all noncommutative spacetimes which are found have com…
Spinors on a curved noncommutative space: coupling to torsion and the Gross-Neveu model
Maja Buric, John Madore, Luka Nenadovic
We analyse the spinor action on a curved noncommutative space, the so-called truncated Heisenberg algebra, and in particular, the nonminimal coupling of spinors to the torsion. We…
On noncommutative spherically symmetric spaces
Maja Buric, John Madore
Two families of noncommutative extensions are given of a general space-time metric with spherical symmetry, both based on the matrix truncation of the functions on the sphere of sy…
Noncommutative geometry of phase space
Maja Buric, John Madore
A version of noncommutative geometry is proposed which is based on phase-space rather than position space. The momenta encode the information contained in the algebra of forms by a…
WKB Approximation in Noncommutative Gravity
Maja Buric, John Madore, George Zoupanos
We consider the quasi-commutative approximation to a noncommutative geometry defined as a generalization of the moving frame formalism. The relation which exists between noncommuta…
The Energy-momentum of a Poisson structure
M. Buric, J. Madore, G. Zoupanos
Consider the quasi-commutative approximation to a noncommutative geometry. It is shown that there is a natural map from the resulting Poisson structure to the Riemann curvature of…
