coupling of topology inflation Noncommutative Cosmology
2011/3/2
We show that, in a model of modi ed gravity based on the spectral action functional, there is a nontrivial coupling between cosmic topology and in ation, in the sense that the shape of the possible sl...
Topology Change and Vector Modules on Noncommutative Surfaces of Rotation
Topology Vector Modules Noncommutative Surfaces of Rotation
2010/10/29
A non associative, noncommutative algebra is defined that may be interpreted as a set of vector modules over a noncommutative surface of rotation. Two of these vector modules are identified with the ...
