Equivariant toric geometry and Euler–Maclaurin formulae

Communications on Pure and Applied Mathematics, Volume 79, Issue 3, Page 451-557, March 2026.
Abstract We first investigate torus‐equivariant motivic characteristic classes of toric varieties, and then apply them via the equivariant Riemann–Roch formalism to prove very general Euler–Maclaurin‐type formulae for full‐dimensional simple lattice polytopes.

Laplace operators on holomorphic Lie algebroids

Analele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2018
The paper introduces Laplace-type operators for functions defined on the tangent space of a Finsler Lie algebroid, using a volume form on the prolongation of the algebroid.

WDVV‐based recursion for open Gromov–Witten invariants

Journal of Topology, Volume 19, Issue 1, March 2026.
Abstract We give a computability result for open Gromov–Witten invariants based on open Witten–Dijkgraaf–Verlinde–Verlinde (WDVV) equations. This is analogous to the result of Kontsevich–Manin for closed Gromov–Witten invariants. For greater generality, we base the argument on a formal object, the Frobenius superpotential, that generalizes several ...

Effective theories for 2+1 dimensional non-Abelian topological spin liquids

Journal of High Energy Physics, 2017
In this work we propose an effective low-energy theory for a large class of 2+1 dimensional non-Abelian topological spin liquids whose edge states are conformal degrees of freedom with central charges corresponding to the coset structure su(2) k ⊕ su(2 ...

Supersymmetry and superstrata in three dimensions

Journal of High Energy Physics, 2021
We analyze the supersymmetry transformations of gauged SO(4) supergravity coupled to extra hypermultiplets in three dimensions, and find large families of smooth BPS solutions that preserve four supersymmetries.

Topological superfluids on a lattice with non-Abelian gauge fields

, 2010
Two-component fermionic superfluids on a lattice with an external non-Abelian gauge field give access to a variety of topological phases in presence of a sufficiently large spin imbalance.

Methodology for Topological Interface Engineering in 2D Photonic Crystals

Advanced Photonics Research, Volume 7, Issue 1, January 2026.
This article introduces an automated framework for topological photonic crystal design. It features an iterative band connection method for identifying band crossings, a data‐driven approach for band symmetry recognition, and analysis of how topological mode dispersion trades off with photonic band‐gap size.

Frobenius 3-Folds via Singular Flat 3-Webs

Symmetry, Integrability and Geometry: Methods and Applications, 2012
We give a geometric interpretation of weighted homogeneous solutions to the associativity equation in terms of the web theory and construct a massive Frobenius 3-fold germ via a singular 3-web germ satisfying the following conditions: 1) the web germ ...

Two Types of Non‐Abelian Topological Phase Transitions Under Duality Mapping in 1D Photonic Chains

Advanced Science, Volume 13, Issue 2, 9 January 2026.
In this work, two types of non‐Abelian phase transitions are revealed. The first type is the braided‐node type, signified by the Dirac degeneracy node moving into or out of the unit circle. The second type corresponds to the emerging of nodal‐line degeneracy which intersects with unit circles.

DFT‐Based Insights Into Elastic, Thermophysical, Electronic, and Optical Properties of Topological Insulators XTe5 (X = Zr, Hf)

Advanced Physics Research, Volume 5, Issue 1, January 2026.
In this work, we present the first in‐depth investigation of elasto‐mechanical, thermophysical, and optical properties of these compounds. In particular, we analyzed the directional dependence of the elastic properties, explored the optical response for different photon polarization directions, and examined potential industrial applications of these ...
