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
