Entropy of (2+1)-dimensional de Sitter black hole to all orders in the Planck length
We calculate the statistical entropy of a scalar field on the background of
(2+1)-dimensional de Sitter space without an artificial cutoff considering
corrections to all orders in the Planck length from a generalized uncertainty
principle (GUP) on the quantum state density. The desired entropy proportional
to the horizon perimeter is obtained.Comment: 10 pages, two references adde
Topological Massive Gauge Theories in Three Dimensions Based on the Faddeev-Jackiw Formalism
We quantize the (2+1)-dimensional self-dual and Maxwell-Chern-Simons theories
by using the Faddeev-Jackiw formulation and compare the results with those of
the Dirac formalism.Comment: 13 Pages, latex, no figure
