Virtual Monopole Geometry and Confinement
HoSeong La
Generalizing the geometry of the gauge covariant variables in Yang-Mills theory proposed by Johnson and Haagensen, the 4-d geometry associated with a monopole is defined for SU(2).…
A Proposal for Low Energy Dilaton
HoSeong La
We propose a systematic way of introducing the (nongravitational) low energy dilaton and a scheme for spontaneous breaking of scale symmetry (SBSS) is explained.
Supersymmetric Dilatations in the Presence of Dilaton
HoSeong La
The supersymmetric generalization of dilatations in the presence of the dilaton is defined. This is done by defining the supersymmetric dilaton geometry which is motivated by the s…
Effective Dilaton Potential in Linearized Gravity
HoSeong La
Considering the linearized gravity with matter fields, the effective potential of the ``conformal dilaton'' in the string frame is generated semiclassically by one-loop contributio…
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…
