Hypergeometric integrals, hook formulas and Whittaker vectors
G. Felder, A. Smirnov, V. Tarasov +1
We determine the coefficient of proportionality between two multidimensional hypergeometric integrals. One of them is a solution of the dynamical difference equations associated wi…
Analyticity of Nekrasov Partition Functions
Giovanni Felder, Martin Müller-Lennert
We prove that the K-theoretic Nekrasov instanton partition functions have a positive radius of convergence in the instanton counting parameter and are holomorphic functions of the…
Regularization of divergent integrals
Giovanni Felder, David Kazhdan
We study the Hadamard finite part of divergent integrals of differential forms with singularities on submanifolds. We give formulae for the dependence of the finite part on the cho…
Gaudin subalgebras and wonderful models
Leonardo Aguirre, Giovanni Felder, Alexander P. Veselov
Gaudin hamiltonians form families of r-dimensional abelian Lie subalgebras of the holonomy Lie algebra of the arrangement of reflection hyperplanes of a Coxeter group of rank r. We…
Zeroes of Wronskians of Hermite polynomials and Young diagrams
G. Felder, A. D. Hemery, A. P. Veselov
For a certain class of partitions, a simple qualitative relation is observed between the shape of the Young diagram and the pattern of zeroes of the Wronskian of the corresponding…
Baker-Akhiezer function as iterated residue and Selberg-type integral
Giovanni Felder, Alexander P. Veselov
A simple integral formula as an iterated residue is presented for the Baker-Akhiezer function related to type root system both in the rational and trigonometric cases. We pre…
Effective Batalin--Vilkovisky theories, equivariant configuration spaces and cyclic chains
Alberto S. Cattaneo, Giovanni Felder
Kontsevich's formality theorem states that the differential graded Lie algebra of multidifferential operators on a manifold M is L-infinity-quasi-isomorphic to its cohomology. The…
Conformal Field Theories on the Two-Torus and Quotients of SL2(Z)
Antoine Coste, Giovanni Felder
We present remarkable properties of the groups SL2(Z/NZ) which might be useful in detailed studies of some quotients appearing in Conformal Field Theories.
