Real higher-order Weyl photonic crystal [PDF]
Nature Communications, 2023 Higher-order Weyl semimetals are a family of recently predicted topological phases simultaneously showcasing unconventional properties derived from Weyl points, such as chiral anomaly, and multidimensional topological phenomena originating from higher ...

THE CHERN–SCHWARTZ–MACPHERSON CLASS OF AN EMBEDDABLE SCHEME [PDF]
Forum of Mathematics, Sigma, 2019 The Chern–Schwartz–MacPherson class of a hypersurface in a nonsingular variety may be computed directly from the Segre class of the Jacobian subscheme of the hypersurface; this has been known for a number of years.

An Algorithm to Compute the Topological Euler Characteristic, Chern-Schwartz-MacPherson Class and Segre Class of Projective Varieties [PDF]
Journal of symbolic computation, 2015 Let $V$ be a closed subscheme of a projective space $\mathbb{P}^n$. We give an algorithm to compute the Chern-Schwartz-MacPherson class, Euler characteristic and Segre class of $ V$.

The order of the top Chern class of the Hodge bundle on the moduli space of abelian varieties [PDF]
, 2004 We give upper and lower bounds for the order of the top Chern class of the Hodge bundle on the moduli space of principally polarized abelian varieties. We also give a generalization to higher genera of the famous formula $12 \lambda_1=\delta$ for genus 1.

Chern class formulas for $G_2$ Schubert loci [PDF]
, 2007 We define degeneracy loci for vector bundles with structure group $G_2$, and give formulas for their cohomology (or Chow) classes in terms of the Chern classes of the bundles involved.

Vaisman manifolds with vanishing first Chern class [PDF]
Journal of the European Mathematical Society (Print), 2023 Compact Vaisman manifolds with vanishing first Chern class split into three categories, depending on the sign of the Bott–Chern class. We show that Vaisman manifolds with non-positive Bott–Chern class admit canonical metrics, are quasi-regular and are ...

Chern currents of coherent sheaves [PDF]
Épijournal de Géométrie Algébrique, 2022 Given a finite locally free resolution of a coherent analytic sheaf $\mathcal F$, equipped with Hermitian metrics and connections, we construct an explicit current, obtained as the limit of certain smooth Chern forms of $\mathcal F$, that represents the ...

Kähler spaces with zero first Chern class: Bochner principle, Albanese map and fundamental groups [PDF]
Journal für die Reine und Angewandte Mathematik, 2020 Let X be a compact Kähler space with klt singularities and vanishing first Chern class. We prove the Bochner principle for holomorphic tensors on the smooth locus of X: any such tensor is parallel with respect to the singular Ricci-flat metrics.
