The gravitational chiral anomaly of spin-1/2 field in the presence of twisted boundary conditions for ordinary field theory
We calculate the chiral anomaly in the neighbourhood of the fixed point space Mh which is constructed by the group action of a discrete symmetry h on a compact manifold M. The Feynman diagrams approach for the corresponding supersymmetric quantum mechanical system with twisted boundary conditions is used. The result we derive in this way agrees with the generalization of the ordinary index theo...

متن کاملNear-field infinity-simulating boundary conditions for the heat equation
The numerical simulation of various physical phenomena in infinite domains poses great difficulties. Truncation of the domain is usually necessary in such cases. To ensure stability of the resulting problem on the restricted domain, appropriate boundary conditions should be applied. Here, we develop a boundary condition for the case in which the heat equation is satisfied outside the domain of ...

متن کاملBoundary Conditions in Rational Conformal Field Theories
We develop further the theory of Rational Conformal Field Theories (RCFTs) on a cylinder with specified boundary conditions emphasizing the role of a triplet of algebras: the Verlinde, graph fusion and Pasquier algebras. We show that solving Cardy’s equation, expressing consistency of a RCFT on a cylinder, is equivalent to finding integer valued matrix representations of the Verlinde algebra. T...
