Nuclear Physics B, 2015 We study the expectation value of a nonplanar Wilson graph operator in SL(2,C) Chern–Simons theory on S3. In particular we analyze its asymptotic behavior in the double-scaling limit in which both the representation labels and the Chern–Simons coupling ...

Interfaces and the extended Hilbert space of Chern-Simons theory
Journal of High Energy Physics, 2020 The low energy effective field theories of (2 + 1) dimensional topological phases of matter provide powerful avenues for investigating entanglement in their ground states.

Solutions of the Strominger System via Stable Bundles on Calabi-Yau Threefolds
, 2012 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.

Deformations of generalized calibrations and compact non-Kähler manifolds with vanishing first Chern class [PDF]
, 2002 We investigate the deformation theory of a class of generalized calibrations in Riemannian manifolds for which the tangent bundle has reduced structure group U(n), SU(n), G_2 and Spin(7). For this we use the property of the associated calibration form to

Chern classes and the periods of mirrors [PDF]
Mathematical Research Letters, 1999 We show how Chern classes of a Calabi Yau hypersurface in a toric Fano manifold can be expressed in terms of the holomorphic at a maximal degeneracy point period of its mirror. We also consider the relation between Chern classes and the periods of mirrors for complete intersections in Grassmanian Gr(2,5).

Journal of High Energy Physics, 2019 We show that an extended 3D Schrödinger algebra introduced in [1] can be reformulated as a 3D Poincaré algebra extended with an SO(2) R-symmetry generator and an SO(2) doublet of bosonic spin-1/2 generators whose commutator closes on 3D translations and ...

Singular Chern Classes of Schubert Varieties via Small Resolution
, 2009 We discuss a method for calculating the Chern-Schwartz-MacPherson (CSM) class of a Schubert variety in the Grassmannian using small resolutions introduced by Zelevinsky.

Chern class formulas for quiver varieties [PDF]
, 1998 In this paper a formula is proved for the general degeneracy locus associated to an oriented quiver of type A_n. Given a finite sequence of vector bundles with maps between them, these loci are described by putting rank conditions on arbitrary composites

Chern Classes of Projective Modules [PDF]
Nagoya Mathematical Journal, 1963 In topology, one can define in several ways the Chern class of a vector bundle over a certain topological space (Chern [2], Hirzebruch [7], Milnor [9], Steenrod [15]). In algebraic geometry, Grothendieck has defined the Chern class of a vector bundle over a non-singular variety.
