Dynamical phase space from a SO(d,d) matrix model
Athanasios Chatzistavrakidis
It is shown that a matrix model with SO(d,d) global symmetry is derived from a generalized Yang-Mills theory on the standard Courant algebroid. This model keeps all the positive fe…
Generalized Yang-Mills theory and the D-brane effective action
Athanasios Chatzistavrakidis, Fridrik Freyr Gautason
Non-abelian gauge theories in the context of generalized complex geometry are discussed. The generalized connection naturally contains standard gauge and scalar fields, unified in…
U-dual branes and mixed symmetry tensor fields
Athanasios Chatzistavrakidis, Fridrik Freyr Gautason
We review and explain the relation between U-dual branes in string theory and mixed symmetry tensors of various degrees. In certain cases these mixed symmetry tensors can be relate…
Phase space quantization, noncommutativity and the gravitational field
Athanasios Chatzistavrakidis
In this paper we study the structure of the phase space in noncommutative geometry in the presence of a nontrivial frame. Our basic assumptions are that the underlying space is a s…
