Research topics

I am interested in scalar-tensor gravity theory, specifically theories that have a local scale symmetry. In 4-d the Lagrangian (first written by Dirac) yields a "frozen up" Dilaton field. In 5-d we using the Kaluza -Klein anzats and reduction (in the vacuum) to find a set of theories characterized by some constant. For different m's different theories arise, where the specific m=-1/3 theory yields a coupling only between the curvature and the Dilaton field. Working in the mini-superspace frame work a wave function can be constructed.
