Instantons and Donaldson-Thomas Invariants
Michele Cirafici, Annamaria Sinkovics, Richard J. Szabo
We review some recent progress in understanding the relation between a six dimensional topological Yang-Mills theory and the enumerative geometry of Calabi-Yau threefolds. The gaug…
Cohomological gauge theory, quiver matrix models and Donaldson-Thomas theory
Michele Cirafici, Annamaria Sinkovics, Richard J. Szabo
We study the relation between Donaldson-Thomas theory of Calabi-Yau threefolds and a six-dimensional topological Yang-Mills theory. Our main example is the topological U(N) gauge t…
Topological Strings, Two-Dimensional Yang-Mills Theory and Chern-Simons Theory on Torus Bundles
N. Caporaso, M. Cirafici, L. Griguolo +3
We study the relations between two-dimensional Yang-Mills theory on the torus, topological string theory on a Calabi-Yau threefold whose local geometry is the sum of two line bundl…
Topological strings and large N phase transitions I: Nonchiral expansion of q-deformed Yang-Mills theory
Nicola Caporaso, Michele Cirafici, Luca Griguolo +3
We examine the problem of counting bound states of BPS black holes on local Calabi-Yau threefolds which are fibrations over a Riemann surface by computing the partition function of…
Morita Duality and Noncommutative Wilson Loops in Two Dimensions
Michele Cirafici, Luca Griguolo, Domenico Seminara +1
We describe a combinatorial approach to the analysis of the shape and orientation dependence of Wilson loop observables on two-dimensional noncommutative tori. Morita equivalence i…
Effective Superpotentials via Konishi Anomaly
L. F. Alday, M. Cirafici
We use Ward identities derived from the generalized Konishi anomaly in order to compute effective superpotentials for SU(N), SO(N) and supersymmetric gauge theories coupled…
