Witten’s top Chern class on the moduli space of higher spin curves [PDF]
This paper is a sequel to [9]. Its goal is to verify that the virtual top Chern class c 1/r in the Chow group of the moduli space of higher spin curves \(\overline M _{{g,n}}^{{1/r}} \) constructed in [9], satisfies all the axioms of spin virtual class ...

Phase transitions in the diagonal ensemble of two-band Chern insulators
We identify a new class of phase transitions when calculating the Hall conductance of two-band Chern insulators in the long-time limit after a global quench of the Hamiltonian.

Orientifold limits of singular F-theory vacua
We construct global orientifold limits of singular F-theory vacua whose associated gauge groups are SO(3), SO(5), SO(6), F4, SU(4), and Spin(7). For each limit we show a universal tadpole relation is satisfied, which is a homological identity whose ...

Chern-Simons type characteristic classes of Abelian lattice gauge theory
In this paper, we extend the definition of the Chern-Simons type characteristic classes in the continuous case to Abelian lattice gauge theory. Then, we show that the exterior differential of the k-th Chern-Simons type characteristic class is exactly ...

New T-duality for Chern-Simons theory
It has recently pointed out that a four-dimensional analog of Chern-Simons theory provides an elegant framework for understanding integrable models with spectral parameters.

Non-K\"ahler Calabi-Yau manifolds
We study the class of compact complex manifolds whose first Chern class vanishes in the Bott-Chern cohomology. This class includes all manifolds with torsion canonical bundle, but it is strictly larger.

Continuity Equation of Transverse Kähler Metrics on Sasakian Manifolds
We introduce the continuity equation of transverse Kähler metrics on Sasakian manifolds and establish its interval of maximal existence. When the first basic Chern class is null (resp. negative), we prove that the solution of the (resp.

The colored Jones polynomials as vortex partition functions
We construct 3D N $$ \mathcal{N} $$ = 2 abelian gauge theories on S $$ \mathbbm{S} $$ 2 × S $$ \mathbbm{S} $$ 1 labeled by knot diagrams whose K-theoretic vortex partition functions, each of which is a building block of twisted indices, give the colored ...

Symplectic structure free Chern-Simons Theory
The second class constraints algebra of the abelian Chern-Simons theory is rigorously studied in terms of the Hamiltonian embedding in order to obtain the first class constraint system.

Solutions of the Strominger System via Stable Bundles on Calabi-Yau Threefolds
We prove that a given Calabi-Yau threefold with a stable holomorphic vector bundle can be perturbed to a solution of the Strominger system provided that the second Chern class of the vector bundle is equal to the second Chern class of the tangent bundle.
