Area Preserving Diffeomorphisms and 2-d Gravity
HoSeong La
Area preserving diffeomorphisms of a 2-d compact Riemannian manifold with or without boundary are studied. We find two classes of decompositions of a Riemannian metric, namely, h-…

Massive Dilaton and Topological Gravity
HoSeong La
A model in which the massive dilaton is introduced by minimally extending the two dimensional topological gravity is studied semi-classically. The theory is no longer topological b…
