Journal ArticleDOI
Witten index, axial anomaly, and Krein's spectral shift function in supersymmetric quantum mechanics
TL;DR: In this article, the spectral shift function, the Witten index, and the anomaly are derived for supersymmetric quantum mechanics using relative scattering techniques, and a complete treatment of the two-dimensional magnetic field problem is given, without assuming that the magnetic flux is quantized.
Journal ArticleDOI
Strong Connections and Chern–Connes Pairing¶in the Hopf–Galois Theory
TL;DR: In this article, the authors reformulated the concept of connection on a Hopf-Galois extension B⊆P in order to apply it in computing the Chern-Connes pairing between the cyclic cohomology HC 2 n 1 (B) and K 1 n 0 (B).
Journal ArticleDOI
Renormalisation of ?4-Theory on Non-Commutative $mathbb{R}(4) $ to All Orders
Harald Grosse,Raimar Wulkenhaar +1 more
TL;DR: In this paper, the duality-covariant four-dimensional non-commutative Φ4 model is renormalisable to all orders, including the free theory by orthogonal polynomials and the renormalisation by flow equations involving power-counting theorems for ribbon graphs drawn on Riemann surfaces.
Journal ArticleDOI
Field theory on the q-deformed fuzzy sphere I
TL;DR: In this article, the authors studied the q-deformed fuzzy sphere, which is related to D-branes on SU(2) WZW models, for both real q and q a root of unity.
Journal ArticleDOI
Renormalization of the noncommutative ϕ3 model through the Kontsevich model
Harald Grosse,Harold Steinacker +1 more
TL;DR: In this article, the noncommutative self-dual ϕ 3 model can be mapped to the Kontsevich model, for a suitable choice of the eigenvalues in the latter.
