Fuzzy-pp Waves
J. Madore, M. Maceda, D. C. Robinson
We present a noncommutative version of a plane-wave solution to the gravitational field equations. We start with a given classical solution, admittedly rather simple, and construct…
Can noncommutativity resolve the Big-Bang singularity?
M. Maceda, J. Madore, P. Manousselis +1
A possible way to resolve the singularities of general relativity is proposed based on the assumption that the description of space-time using commuting coordinates is not valid ab…
On the Wheeler-DeWitt equation for Kasner-like Cosmologies
M. Maceda
The Wheeler-DeWitt equation is obtained for Kasner-like cosmologies. Some solutions to this equation are presented for empty space, space filled with a cosmological constant and in…
Contact Geometry in Superconductors and New Massive Gravity
D. Flores-Alfonso, C. S. Lopez-Monsalvo, M. Maceda
The defining property of every three-dimensional -contact manifold is shown to be equivalent to requiring the fulfillment of London's equation in 2+1 electromagnetism.…
Metrics on the Real Quantum Plane
G. Fiore, M. Maceda, J. Madore
Using the frame formalism we determine some possible metrics and metric-compatible connections on the noncommutative differential geometry of the real quantum plane. By definition…
Thurston Geometries in Three-Dimensional New Massive Gravity
D. Flores-Alfonso, C. S. Lopez-Monsalvo, M. Maceda
We show that the three-dimensional Thurston geometries are vacuum solutions to the 3D new massive gravity equations of motion. We analyze their Lorentzian counterparts as well.
