Chern Classes of Splayed Intersections [PDF]
Canadian Journal of Mathematics, 2015 AbstractWe generalize the Chern class relation for the transversal intersection of two nonsingular varieties to a relation for possibly singular varieties, under a splayedness assumption. We show that the relation for the Chern–Schwartz–MacPherson classes holds for two splayed hypersurfaces in a nonsingular variety, and under a strong splayedness ...

Journal of High Energy Physics, 2021 We study the interplay between four-derivative 4d gauged supergravity, holography, wrapped M5-branes, and theories of class ℛ $$ \mathrm{\mathcal{R}} $$ .

THE BIG CHERN CLASSES AND THE CHERN CHARACTER [PDF]
International Journal of Mathematics, 2008 Let X be a smooth scheme over a field of characteristic 0. The Atiyah class of the tangent bundle TXof X equips TX[-1] with the structure of a Lie algebra object in the derived category D+(X) of bounded below complexes of [Formula: see text] modules with coherent cohomology [6]. We lift this structure to that of a Lie algebra object [Formula: see text]

Geophysical Monograph Series, Page 169-190., 2021 Exploring the links between Large Igneous Provinces and dramatic environmental impact
An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Chern classes and generators [PDF]
Proceedings of the Japan Academy, Series A, Mathematical Sciences, 2012 We give a simple proof for the fact that algebra generators of the mod 2 cohomology of classifying spaces of exceptional Lie groups are given by Chern classes and Stiefel-Whitney classes of certain representations.

The Kodaira Problem for Kähler Spaces with Vanishing First Chern Class
Forum of Mathematics, Sigma, 2021 Let X be a normal compact Kähler space with klt singularities and torsion canonical bundle. We show that X admits arbitrarily small deformations that are projective varieties if its locally trivial deformation space is smooth.

The Chern-Ricci flow on complex surfaces [PDF]
, 2012 The Chern-Ricci flow is an evolution equation of Hermitian metrics by their Chern-Ricci form, first introduced by Gill. Building on our previous work, we investigate this flow on complex surfaces. We establish new estimates in the case of finite time non-

Radiatively Induced Lorentz and CPT Violation in Electrodynamics [PDF]
, 1999 In a nonperturbative formulation, radiative corrections arising from Lorentz and CPT violation in the fermion sector induce a definite and nonzero Chern-Simons addition to the electromagnetic action.

Foliations with vanishing Chern classes [PDF]
Bulletin of the Brazilian Mathematical Society, New Series, 2013 In this paper we aim at the description of foliations having tangent sheaf $T\mathcal F$ with $c_1(T\mathcal F)=c_2(T\mathcal F)=0$ on non-uniruled projective manifolds. We prove that the universal covering of the ambient manifold splits as a product, and that the Zariski closure of a general leaf of $\mathcal F$ is an Abelian variety.

Non-invertible symmetries of class S theories
Journal of High Energy Physics, 2023 We study the non-invertible symmetries of class S $$ \mathcal{S} $$ theories obtained by compactifying the type a p − 1 $$ {\mathfrak{a}}_{p-1} $$ 6d (2,0) theory on a genus g Riemann surface with no punctures.
