Order recognition by Schubert polynomials generated by optical near-field statistics via nanometre-scale photochromism

Scientific Reports, 2022
Irregular spatial distribution of photon transmission through a photochromic crystal photoisomerized by a local optical near-field excitation was previously reported, which manifested complex branching processes via the interplay of material deformation ...

Sharp Focusing of a Hybrid Vector Beam with a Polarization Singularity

Photonics, 2021
The key result of this work is the use of the global characteristics of the polarization singularities of the entire beam as a whole, rather than the analysis of local polarization, Stokes and Poincare–Hopf indices.

Codimension-3 Singularities and Yukawa Couplings in F-theory [PDF]

, 2009
F-theory is one of the frameworks where all the Yukawa couplings of grand unified theories are generated and their computation is possible. The Yukawa couplings of charged matter multiplets are supposed to be generated around codimension-3 singularity ...

Application of singularity theory and logistic regression model for tungsten polymetallic potential mapping [PDF]

Nonlinear Processes in Geophysics, 2013
Geo-anomalies with complex structures in the earth's crust may be defined as preferable hydrothermal ore-forming targets. The separation and explanation of anomaly from geological background have a profound influence on the analysis of geological ...

The Bell states in noncommutative algebraic geometry [PDF]

, 2014
We introduce new mathematical aspects of the Bell states using matrix factorizations, nonnoetherian singularities, and noncommutative blowups. A matrix factorization of a polynomial $p$ consists of two matrices $\phi_1,\phi_2$ such that $\phi_1\phi_2 ...

The local analytical triviality of a complex analytic singular foliation

Hokkaido Mathematical Journal, 2004
The authors investigate complex analytic singular foliations defined on the complex analytic manifold \(M\) of dimension \(n\). After recalling basic notions of the theory of singular foliations they prove a theorem about local analytic triviality along the leaves. The main tool of the proof is the Whitney stratification of the singular locus. The last

Extending holomorphic forms from the regular locus of a complex space to a resolution of singularities

, 2020
We investigate under what conditions holomorphic forms defined on the regular locus of a reduced complex space extend to holomorphic (or logarithmic) forms on a resolution of singularities.

Equivariant Hirzebruch class for singular varieties [PDF]

, 2015
The Hirzebruch $td_y(X)$ class of a complex manifold X is a formal combination of Chern characters of the sheaves of differential forms multiplied by the Todd class.

A Parametric Shape Model Applied to Tracing the Migration of the Objects Near an Asteroid

Earth and Space Science, 2021
In the past decades, space missions to small bodies (Galileo, OSIRIS‐REx, Hayabusa, Hayabusa2, Chang'e 2, Rosetta, etc.) have enriched us greatly with voluminous new knowledge on our solar system.

Classification of rational unicuspidal curves with two Newton pairs [PDF]

, 2015
Based on Tiankai Liu's PhD thesis (MIT, 2014), we give a complete classification of local topological types of singularities with two Newton pairs on rational unicuspidal complex projective plane curves.
