Recent Developments in (0,2) Mirror Symmetry

Symmetry, Integrability and Geometry: Methods and Applications, 2012
Mirror symmetry of the type II string has a beautiful generalization to the heterotic string. This generalization, known as (0,2) mirror symmetry, is a field still largely in its infancy. We describe recent developments including the ideas behind quantum

Tangential Quantum Cohomology of Arbitrary Order

, 2007
J. Kock has previously defined a tangency quantum product on formal power series with coefficients in the cohomology ring of any smooth projective variety, and thus a ring that generalizes the quantum cohomology ring.

The shape of non-graviton operators for SU(2)

Journal of High Energy Physics
The BPS spectrum of AdS/CFT exhibits multi-gravitons at low energies, while having black hole states at higher energies. This can be studied concretely in AdS5/CFT4 in terms of classical cohomologies, even in the quantum regimes at finite 1/N.

Engineering of anyons on M5-probes via flux quantization

SciPost Physics Lecture Notes
These extended lecture notes survey a novel derivation of anyonic topological order (as seen in fractional quantum Hall systems) on single magnetized M5-branes probing Seifert orbi-singularities ("geometric engineering" of anyons), which we motivate from

Topological Insulators from Group Cohomology

Physical Review X, 2016
We classify insulators by generalized symmetries that combine space-time transformations with quasimomentum translations. Our group-cohomological classification generalizes the nonsymmorphic space groups, which extend point groups by real-space ...

Enlargement of Symmetry Groups in Physics: A Practitioner’s Guide

Universe
Wigner’s classification has led to the insight that projective unitary representations play a prominent role in quantum mechanics. The physics literature often states that the theory of projective unitary representations can be reduced to the theory of ...

Kodaira-Spencer maps for elliptic orbispheres as isomorphisms of Frobenius algebras

Open Mathematics
Given a mirror pair of a symplectic manifold X and a Landau-Ginzburg potential W, we are interested in whether the quantum cohomology of X and the Jacobian algebra of W are isomorphic.

Coordinate rings of regular nilpotent Hessenberg varieties in the open opposite schubert cell

Forum of Mathematics, Sigma
Dale Peterson has discovered a surprising result that the quantum cohomology ring of the flag variety $\operatorname {\mathrm {GL}}_n({\mathbb {C}})/B$ is isomorphic to the coordinate ring of the intersection of the Peterson variety ...
