Instanton counting with a surface operator and the chain-saw quiver
Hiroaki Kanno, Yuji Tachikawa
We describe the moduli space of SU(N) instantons in the presence of a general surface operator of type N=n_1+ ... +n_M in terms of the representations of the so-called chain-saw qu…
Instanton Calculus and Loop Operator in Supersymmetric Gauge Theory
Hiroaki Kanno, Sanefumi Moriyama
We compute one-point function of the glueball loop operator in the maximally confining phase of supersymmetric gauge theory using instanton calculus. In the maximally confining pha…
Universal Character and Large N Factorization in Topological Gauge/String Theory
Hiroaki Kanno
We establish a formula of the large N factorization of the modular S-matrix for the coupled representations in U(N) Chern-Simons theory. The formula was proposed by Aganagic, Neitz…
Instanton counting, Macdonald function and the moduli space of D-branes
Hidetoshi Awata, Hiroaki Kanno
We argue the connection of Nekrasov's partition function in the Ωbackground and the moduli space of D-branes, suggested by the idea of geometric engineering and Gopakumar-Vafa inva…
Geometric transitions, Chern-Simons gauge theory and Veneziano type amplitudes
Tohru Eguchi, Hiroaki Kanno
We consider the geometric transition and compute the all-genus topological string amplitudes expressed in terms of Hopf link invariants and topological vertices of Chern-Simons gau…
Topological Strings and Nekrasov's formulas
Tohru Eguchi, Hiroaki Kanno
We apply the method of geometric transition and compute all genus topological closed string amplitudes compactified on local {\bf F}_0 by making use of the Chern-Simons gauge theor…
