Uniform semiclassical approximation in quantum statistical mechanics
We present a simple method to deal with caustics in the semiclassical
approximation to the partition function of a one-dimensional quantum system.
The procedure, which makes use of complex trajectories, is applied to the
quartic double-well potential.Comment: 5 pages, 1 figure, Latex. Contribution to the Proceedings of the XXI

Notes on interacting holographic dark energy model in a closed universe
We consider interacting holographic dark energy model in Friedmann Robertson
Walker space time with positive spatial curvature and investigate the behavior
of curvature parameter and dark energy density in accelerated expanding epoch.
We also derive some conditions needed to cross the phantom divide line in this
model.Comment: 10 pages, typos corrected, some explanations and references added and
