Continuing with our previous series of work, we present a case study of the critical phenomena around Argyres-Douglas singularity of N=2 susy made at (A1,A4k−1),k=1,2 realized by one-unitary matrix model. We determine the phase diagram, which is re

A sequence of massive scaling limits of the β-deformed An−1 quiver matrix model that keeps the size of the matrices finite and that corresponds to the Nf=2n→2n−1,2n−2 limits on the number of flavors at 4d su(n) N=2 SUSY gauge theory side is

Abstract A novel functorial relationship in perturbative quantum field theory is pointed out that associates Feynman diagrams (FD) having no external line in one theory $$\mathbf{Th}_1$$ Th1 with singlet operators in another one $$\mathbf{Th}_2$$ Th2

T-dualities of the non-supersymmetric string models, which are constructed by twisted compactifications, are investigated. We show that the T-duality groups of such models are obtained by imposing congruence conditions on O(dL,dR,Z), that is, the non

Abstract In rainbow tensor models, which generalize rectangular complex matrix model (RCM) and possess a huge gauge symmetry U(N 1) × … × U(N r ), we introduce a new sub-basis in the linear space of gauge invariant operators, which is a redundant

We study the partition function of the matrix model of finite size that realizes the irregular conformal block for the case of the N=2 supersymmetric SU(2) gauge theory with Nf=2. This model has been obtained in arXiv:1008.1861 [hep-th] as the massiv

We present a brief summary of the recent discovery of direct tensorial analogue of characters. We distinguish three degrees of generalization: (1) c-number Kronecker characters made with the help of symmetric group characters and inheriting most of t

Following our previous work of 1905.10745 [hep-th], 2003.11217 [hep-th], we study heterotic interpolating models D dimensionally compactified with constant background fields that include the full set of Wilson lines and radii. Focusing on the phenome

We investigate the structure of the moduli space of 9D heterotic interpolating models with a complete set of Wilson line backgrounds and a radius parameter by computing the one-loop partition functions and the cosmological constants and by deriving t

Similarly to the complex matrix model, the rainbow tensor models are superintegrable in the sense that arbitrary Gaussian correlators are explicitly expressed through the Clebsh-Gordan coefficients. We introduce associated (Ooguri-Vafa type) partitio
