ECH capacities, Ehrhart theory, and toric varieties [PDF]

open access: yesThe Journal of Symplectic Geometry, 2019
ECH capacities were developed by Hutchings to study embedding problems for symplectic $4$-manifolds with boundary. They have found especial success in the case of certain toric symplectic manifolds where many of the computations resemble calculations ...

Intersection spaces and toric varieties [PDF]

open access: yes, 2023
In the first part of the work, we study the topological aspects of compact toric varieties. Considering toric varieties as pseudomanifolds, we investigate their standard stratification. We prove the triviality of the link bundles of toric varieties. On

ON TORUS ACTIONS OF HIGHER COMPLEXITY

open access: yesForum of Mathematics, Sigma, 2019
We systematically produce algebraic varieties with torus action by constructing them as suitably embedded subvarieties of toric varieties. The resulting varieties admit an explicit treatment in terms of toric geometry and graded ring theory. Our approach

Toric matrix Schubert varieties and root polytopes (extended abstract) [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2020
Start with a permutation matrix π and consider all matrices that can be obtained from π by taking downward row operations and rightward column operations; the closure of this set gives the matrix Schubert variety Xπ.

Nearest points on toric varieties [PDF]

open access: yesMATHEMATICA SCANDINAVICA, 2018
We determine the Euclidean distance degree of a projective toric variety. This extends the formula of Matsui and Takeuchi for the degree of the $A$-discriminant in terms of Euler obstructions. Our primary goal is the development of reliable algorithmic tools for computing the points on a real toric variety that are closest to a given data point.

SU(3) structures on S2 bundles over four-manifolds

open access: yesJournal of High Energy Physics, 2017
We construct globally-defined SU(3) structures on smooth compact toric varieties (SCTV) in the class of ℂ ℙ 1 $$ \mathbb{C}{\mathrm{\mathbb{P}}}^1 $$ bundles over M , where M is an arbitrary SCTV of complex dimension two. The construction can be extended

FORMATION OF MODERN MATHEMATICAL APPROACH TO SOLVING PROBLEMS OF PHYSICS

open access: yesФізико-математична освіта, 2022
Formulation of the problem. Precision studies of the Higgs boson, supersymmetric particles, the magnetic moment of the muon, electric dipole moment of the electron, flavor anomalies demonstrate the deviation beyond Standard Model. They are connected with
