A Search for Non-Perturbative Dualities of Local Yang--Mills Theories from Calabi--Yau Threefolds
A. Ceresole, M. Billo', R. D'Auria +5
The generalisation of the rigid special geometry of the vector multiplet quantum moduli space to the case of supergravity is discussed through the notion of a dynamical Calabi--Yau…
R-Symmetry and the Topological Twist of N=2 Effective Supergravities of Heterotic Strings
M. Billo', R. D'Auria, S. Ferrara +3
We discuss R-symmetries in locally supersymmetric N=2 gauge theories coupled to hypermultiplets which can be thought of as effective theories of heterotic superstring models. In th…
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…
Topological First-Order Systems with Landau-Ginzburg Interactions
P. Fre', L. Girardello, A. Lerda +1
We consider the realization of N=2 superconformal models in terms of free first-order -systems, and show that an arbitrary Landau-Ginzburg interaction with quasi-homogen…
