Dimensional Reduction of the Heterotic String over nearly-Kaehler manifolds
Athanasios Chatzistavrakidis, George Zoupanos
Our aim is to derive the effective action in four dimensions resulting by reducing dimensionally the ten-dimensional heterotic supergravity coupled to sup…
Unified Gauge Theories and Reduction of Couplings: from Finiteness to Fuzzy Extra Dimensions
Myriam Mondragon, George Zoupanos
Finite Unified Theories (FUTs) are N=1 supersymmetric Grand Unified Theories, which can be made all-loop finite, both in the dimensionless (gauge and Yukawa couplings) and dimensio…
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…
On the consistency of coset space dimensional reduction
Athanasios Chatzistavrakidis, Pantelis Manousselis, Nikolaos Prezas +1
In this letter we consider higher-dimensional Yang-Mills theories and examine their consistent coset space dimensional reduction. Utilizing a suitable ansatz and imposing a simple…
Fermions on spontaneously generated spherical extra dimensions
Harold Steinacker, George Zoupanos
We include fermions to the model proposed in hep-th/0606021, and obtain a renormalizable 4-dimensional SU(N) gauge theory which spontaneously generates fuzzy extra dimensions and b…
