Topological Invariance of the Witten Index
We discuss the Witten index in terms of Krein's spectral shift function, and prove invariance of the Witten index under suitable relative trace class hypotheses.
متن کاملOn the forgotten topological index
The forgotten topological index is defined as sum of third power of degrees. In this paper, we compute some properties of forgotten index and then we determine it for some classes of product graphs.
متن کاملCobordism Invariance of the Index
We give a proof of the cobordism invariance of the index of elliptic pseudodifferential operators on σ-compact manifolds, where, in the non-compact case, the operators are assumed to be multiplication outside a compact set. We show that, if the principal symbol class of such an elliptic operator on the boundary of a manifold X has a suitable extension to K1(TX), then its index is zero. This con...
متن کاملMass, Confinement and CP Invariance in the Seiberg-Witten Model
Several physics aspects of the Seiberg-Witten solution of N = 2 supersymmetric Yang-Mills theory with SU(2) gauge group, supplemented with a small mass term for the ”matter” fields which leads to an N = 1 theory with confinement, are discussed. The light spectrum of the theory is understood on the basis of current algebra relations, and the θ parameter dependence of the massless and massive the...
متن کامل6 Witten Deformation and the Equivariant Index
Let M be a compact Riemannian manifold endowed with an isometric action of a compact Lie group. The method of the Witten deformation is used to compute the virtual representation-valued equivariant index of a transversally elliptic, first order differential operator on M. The multiplicities of irreducible representations in the index are expressed in terms of local quantities associated to the ...
