BRS symmetry from renormalization group flow
M. Bonini, M. D'Attanasio, G. Marchesini
By using the exact renormalization group formulation we prove perturbatively the Slavnov-Taylor (ST) identities in SU(2) Yang-Mills theory. This results from two properties: {\it l…
A Matrix Model for Random Surfaces with Dynamical Holes
G. M. Cicuta, L. Molinari, E. Montaldi +1
A matrix model to describe dynamical loops on random planar graphs is analyzed. It has similarities with a model studied by Kazakov, few years ago, and the O(n) model by Kostov and…
BRS symmetry for Yang-Mills theory with exact renormalization group
M. Bonini, M. D'Attanasio, G. Marchesini
In the exact renormalization group (RG) flow in the infrared cutoff one needs boundary conditions. In a previous paper on Yang-Mills theory we proposed to use the nine…
Three-dimensional BF Theories and the Alexander-Conway Invariant of Knots
A. S. Cattaneo, P. Cotta-Ramusino, M. Martellini
We study 3-dimensional BF theories and define observables related to knots and links. The quantum expectation values of these observables give the coefficients of the Alexander-Con…
Topological Correlation Functions in Minkowski Spacetime
S. Penati, D. Zanon
We consider a class of non-unitary Toda theories based on the Lie superalgebras in two-dimensional Minkowski spacetime, which can be twisted into a topological secto…
Unified Approach to Thermodynamic Bethe Ansatz and Finite Size Corrections for Lattice Models and Field Theories
C. Destri, H. J. de Vega
We present a unified approach to the Thermodynamic Bethe Ansatz (TBA) for magnetic chains and field theories that includes the finite size (and zero temperature) calculations for l…
Constrained Topological Field Theory
Damiano Anselmi, Pietro Fre', Luciano Girardello +1
We derive a model of constrained topological gravity, a theory recently introduced by us through the twist of N=2 Liouville theory, starting from the general BRST algebra and impos…
From N=2 Supergravity to Constrained Moduli Spaces
D. Anselmi, P. Fre', L. Girardello +1
In this talk we review some results concerning a mechanism for reducing the moduli space of a topological field theory to a proper submanifold of the ordinary moduli space. Such me…
Constrained Topological Gravity from Twisted N=2 Liouville Theory
D. Anselmi, P. Fre', L. Girardello +1
In this paper we show that there exists a new class of topological field theories, whose correlators are intersection numbers of cohomology classes in a constrained moduli space. O…
Kahler Potentials and Renormalization Group Flows in N=2 Landau-Ginzburg Models
M. T. Grisaru, D. Zanon
We examine the conditions for superconformal invariance and the specific form of the Kähler potential for a two-dimensional lagrangian model with supersymmetry and superpoten…
Axial anomalies in gauge theory by exact renormalization group method
M. Bonini, M. D'Attanasio, G. Marchesini
The global chiral symmetry of a gauge theory is studied in the framework of renormalization group (RG). The theory is defined by the RG flow equations in the infrared cutof…
Moduli Spaces of Curves with Homology Chains and c=1 Matrix Models
A. S. Cattaneo, A. Gamba, M. Martellini
We show that introducing a periodic time coordinate in the models of Penner-Kontsevich type generalizes the corresponding constructions to the case of the moduli space ${\cal S}_{g…
Exact renormalization group equation and decoupling in quantum field theory
L. Girardello, A. Zaffaroni
New proves of decoupling of massive fields in several quantum field theories are derived in the effective Lagrangian approach based on Wilson renormalization group. In the most int…
A consistent derivation of the quark--antiquark and three quark potentials in a Wilson loop context
N. Brambilla, P. Consoli, G. M. Prosperi
In this paper we give a new derivation of the quark-antiquark potential in the Wilson loop context. This makes more explicit the approximations involved and enables an immediate ex…
