Mutation and crossover of simplicial complexes

Boyu Li, Kohta Hatakeyama, Matsuo Sato +2

Color graphs and their subgraphs, referred to as bubble graphs, correspond bijectively to the simplicial complexes of pseudomanifolds and their subsimplices, respectively. In this…

Blowup Equations for Little Strings

Hee-Cheol Kim, Minsung Kim, Yuji Sugimoto

We propose blowup equations for 6d little string theories which generalize Nakajima-Yoshioka's blowup equations for the 4d/5d instanton partition functions on Omega background. We…

-type little strings from glued brane webs

Sung-Soo Kim, Yuji Sugimoto, Xing-Yue Wei +1

We propose brane web configurations for -type and -type little string theories based on a trivalent or quadrivalent gluing of 5-brane web diagrams. Tri-/q…

Path-integrals of perturbative superstrings on curved backgrounds from string geometry theory

Matsuo Sato, Kunihito Uzawa

String geometry theory is one of the candidates of the non-perturbative formulation of string theory. In this paper, from the string geometry theory, we derive path-integrals of pe…

Branes, quivers and wave-functions

Taro Kimura, Miłosz Panfil, Yuji Sugimoto +1

We consider a large class of branes in toric strip geometries, both non-periodic and periodic ones. For a fixed background geometry we show that partition functions for such branes…

Surface defects on E-string from 5-brane webs

Sung-Soo Kim, Yuji Sugimoto, Futoshi Yagi

We study 6d E-string theory with defects on a circle. Our basic strategy is to apply the geometric transition to the supersymmetric gauge theories. First, we calculate the partitio…

Topological Vertex/anti-Vertex and Supergroup Gauge Theory

Taro Kimura, Yuji Sugimoto

We propose a new vertex formalism, called anti-refined topological vertex (anti-vertex for short), to compute the generalized topological string amplitude, which gives rise to the…

Quantum Mirror Map for Del Pezzo Geometries

Tomohiro Furukawa, Sanefumi Moriyama, Yuji Sugimoto

Mirror maps play an important role in studying supersymmetric gauge theories. In these theories the dynamics is often encoded in an algebraic curve where two sets of periods enjoy…
