Operator product expansion for conformal defects
Masayuki Fukuda, Nozomu Kobayashi, Tatsuma Nishioka
We study the operator product expansion (OPE) for scalar conformal defects of any codimension in CFT. The OPE for defects is decomposed into "defect OPE blocks", the irreducible re…
Reflection states in Ding-Iohara-Miki algebra and brane-web for D-type quiver
Jean-Emile Bourgine, Masayuki Fukuda, Yutaka Matsuo +1
Reflection states are introduced in the vertical and horizontal modules of the Ding-Iohara-Miki (DIM) algebra (quantum toroidal ). Webs of DIM representations are…
Maulik-Okounkov's R-matrix from Ding-Iohara-Miki algebra
Masayuki Fukuda, Koichi Harada, Yutaka Matsuo +1
The integrability of 4d gauge theories has been explored in various contexts, for example the Seiberg-Witten curve and its quantization. Recently, Maulik and Okounk…
(p,q)-webs of DIM representations, 5d N=1 instanton partition functions and qq-characters
Jean-Emile Bourgine, Masayuki Fukuda, Koichi Harada +2
Instanton partition functions of 5d Super Yang-Mills reduced on can be engineered in type IIB string theory from the -branes web diagram. To this diagr…
