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
On the anomaly of nonlocal symmetry in the chiral QED
We show that the anomaly of nonlocal symmetry can be canceled by the
well-known Wess-Zumino acton which cancels the gauge anomaly in the
two-dimensional chiral electrodynamics.Comment: 4 pages, latex, no figure
