RR charges of D2-branes in the WZW model
Anton Alekseev, Volker Schomerus
We consider the contribution of the B-field into the RR charge of a spherical D2-brane. Extending a recent analysis of Taylor, we show that the boundary and bulk contributions do n…
On area and entropy of a black hole
A. Alekseev, A. P. Polychronakos, M. Smedbäck
We consider a model of a black hole consisting of a number of elementary components. Examples of such models occur in the Ashtekar's approach to canonical Quantum Gravity and in M-…
Wilson lines on noncommutative tori
Anton Alekseev, Andrei Bytsko
We introduce the notion of a monodromy for gauge fields with vanishing curvature on the noncommutative torus. Similar to the ordinary gauge theory, traces of the monodromies define…
Closed constraint algebras and path integrals for loop group actions
A. Y. Alekseev, V. Schomerus, T. Strobl
In this note we study systems with a closed algebra of second class constraints. We describe a construction of the reduced theory that resembles the conventional treatment of first…
