Ω-Background and the Nekrasov Partition Function
In this talk we’ll aim to make sense of the Nekrasov partition function (as introduced in Nekrasov’s ICM address [Nek03]) as the partition function in a twisted deformed N = 2 gauge theory. While making the deformation is unnecessary – without it we’re just talking about the partition function in Donaldson-Witten theory – deforming the theory eliminates IR divergences, allowing a direct mathema...
متن کاملGiants On Deformed Backgrounds
We study giant graviton probes in the framework of the three–parameter deformation of the AdS5 × S background. We examine both the case when the brane expands in the deformed S̃ part of the geometry and the case when it blows up into AdS5. Performing a detailed analysis of small fluctuations around the giants, the configurations turn out to be stable. Our results hold even for the supersymmetric...
متن کاملTopological Partition Function and String-String Duality
The evidence for string/string-duality can be extended from the matching of the vector couplings to gravitational couplings. In this note this is shown in the rank three example, the closest stringy analog of the Seiberg/Witten-setup, which is related to the Calabi-Yau WP 4 1,1,2,2,6(12). I provide an exact analytical verification of a relation checked by coefficient comparison to fourth order ...
متن کاملTopological Entanglement Entropy from the Holographic Partition Function
We study the entropy of chiral 2+1-dimensional topological phases, where there are both gapped bulk excitations and gapless edge modes. We show how the entanglement entropy of both types of excitations can be encoded in a single partition function. This partition function is holographic because it can be expressed entirely in terms of the conformal field theory describing the edge modes. We giv...
متن کاملOn a Deformed Topological Vertex
Recall the topological vertex involves three partitions, when one of them is empty it is related to the leading term of the large N colored HOMFLY polynomials of the Hopf link, and the general topological vertex can be expressed in terms of such leading terms. We will use the whole colored HOMFLY polynomials to define the deformed vertex, hence deformations of the partition functions of topolog...
