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 کاملRestricted integer partition functions
For two sets A and M of positive integers and for a positive integer n, let p(n,A,M) denote the number of partitions of n with parts in A and multiplicities in M , that is, the number of representations of n in the form n = ∑ a∈Amaa where ma ∈M ∪{0} for all a, and all numbers ma but finitely many are 0. It is shown that there are infinite sets A and M so that p(n,A,M) = 1 for every positive int...
متن کاملGeneralised twisted partition functions
We consider the set of partition functions that result from the insertion of twist operators compatible with conformal invariance in a given 2D Conformal Field Theory (CFT). A consistency equation, which gives a classification of twists, is written and solved in particular cases. This generalises old results on twisted torus boundary conditions, gives a physical interpretation of Ocneanu's alge...
متن کاملD-instanton partition functions
Duality arguments are used to determine D-instanton contributions to certain effective interaction terms of type II supergravity theories in various dimensions. This leads to exact expressions for the partition functions of the finite N D-instanton matrix model in d = 4 and 6 dimensions that generalize our previous expression for the case d = 10. These results are consistent with the fact that ...
متن کاملMOLECULAR PARTITION FUNCTIONS Introduction
In the last chapter, we have been introduced to the three main ensembles used in statistical mechanics and some examples of calculations of partition functions were also given. In chemistry, we are concerned with a collection of molecules. If the molecules are reasonably far apart as in the case of a dilute gas, we can approximately treat the system as an ideal gas system and ignore the intermo...
