Algebra of Kodaira-Spencer Gravity and Deformation of Calabi-Yau Manifold
Kenji Mohri
We study the algebraic structure of the configuration space of the Kodaira-Spencer gravity theory on a Calabi-Yau threefold. We then investigate the deformation problem of the Koda…
Five-dimensional Supergravity and Hyperbolic Kac-Moody Algebra G2H
Shun'ya Mizoguchi, Kenji Mohri, Yasuhiko Yamada
Motivated by the recent analysis of the E10 sigma model for the study of M theory, we study a one-dimensional sigma model associated with the hyperbolic Kac-Moody algebra G2H and i…
Exceptional String: Instanton Expansions and Seiberg-Witten Curve
Kenji Mohri
We investigate instanton expansions of partition functions of several toric E-string models using local mirror symmetry and elliptic modular forms. We also develop a method to obta…
Closed Sub-Monodromy Problems, Local Mirror Symmetry and Branes on Orbifolds
Kenji Mohri, Yoko Onjo, Sung-Kil Yang
We study D-branes wrapping an exceptional four-cycle P(1,a,b) in a blown-up C^3/Z_m non-compact Calabi-Yau threefold with (m;a,b)=(3;1,1), (4;1,2) and (6;2,3). In applying the meth…
Duality Between String Junctions and D-Branes on Del Pezzo Surfaces
Kenji Mohri, Yukiko Ohtake, Sung-Kil Yang
We revisit local mirror symmetry associated with del Pezzo surfaces in Calabi-Yau threefolds in view of five-dimensional N=1 E_N theories compactified on a circle. The mirror partn…
Kähler Moduli Space of a D-Brane at Orbifold Singularities
Kenji Mohri
We develop a method to analyze systematically the configuration space of a D-brane localized at the orbifold singular point of a Calabi--Yau -fold of the form usi…
D-Branes and Quotient Singularities of Calabi-Yau Fourfolds
Kenji Mohri
We investigate a (0,2) gauge theory realized on the world volume of the type IIB D1-brane at the singular point of a Calabi-Yau fourfold. It is argued that the gauge anomaly can be…
F theory Vacua in Four Dimensions and Toric Threefolds
Kenji Mohri
We investigate D=4, N=1 F theory models realized by type IIB string compactification on toric threefolds. Massless spectra, gauge symmetries, phase transitions associated with divi…
Residues and Topological Yang-Mills Theory in Two Dimensions
Kenji Mohri
A residue formula which evaluates any correlation function of topological Yang-Mills theory with arbitrary magnetic flux insertion in two dimensions are obtained. Deformatio…
Geometry of (0,2) Landau-Ginzburg Orbifolds
Toshiya Kawai, Kenji Mohri
Several aspects of (0,2) Landau-Ginzburg orbifolds are investigated. Especially the elliptic genera are computed in general and, for a class of models recently invented by Distler…
super algebra in half-twisted Landau-Ginzburg model
Kenji Mohri
We investigate extended superconformal symmetry, using the half-twisted Landau-Ginzburg models. The first example is the -type minimal model. It has been conjectur…
