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

open access: yesUniverse
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 access: yesOpen 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

open access: yesForum 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 ...

Les Houches lecture notes on moduli spaces of Riemann surfaces

open access: yesSciPost Physics Lecture Notes
In these lecture notes, we provide an introduction to the moduli space of Riemann surfaces, a fundamental concept in the theories of 2D quantum gravity, topological string theory, and matrix models. We begin by reviewing some basic results concerning the

Quantum Dynamics on the Worldvolume from Classical su(n) Cohomology

open access: yesSymmetry, Integrability and Geometry: Methods and Applications, 2008
A key symmetry of classical p-branes is invariance under worldvolume diffeomorphisms. Under the assumption that the worldvolume, at fixed values of the time, is a compact, quantisable Kähler manifold, we prove that the Lie algebra of volume-preserving ...
