Intersection numbers on M ¯ g , n $$ {\overline{M}}_{g,n} $$ and BKP hierarchy
Journal of High Energy Physics, 2021 In their recent inspiring paper, Mironov and Morozov claim a surprisingly simple expansion formula for the Kontsevich-Witten tau-function in terms of the Schur Q-functions.

Intersections of twisted forms: New theories and double copies
Nuclear Physics B, 2023 Tree–level scattering amplitudes of particles have a geometrical description in terms of intersection numbers of pairs of twisted differential forms on the moduli space of Riemann spheres with punctures.

Intersection numbers of polygon spaces [PDF]
Transactions of the American Mathematical Society, 2009 We study the intersection ring of the space M ( α 1 , … , α m ) \mathcal {M}(\alpha _1,\ldots ,\alpha _m) of polygons in R 3 \mathbb {R}^3 .

Intersection graphs of graded ideals of graded rings
AIMS Mathematics, 2021 In this article, we introduce and study the intersection graph of graded ideals of a graded ring. The intersection graph of G−graded ideals of a graded ring R, denoted by GrG(R), is undirected simple graph defined on the set of nontrivial graded left ...

Generating functions for intersection products of divisors in resolved F-theory models
Nuclear Physics B, 2023 Building on the approach of 1703.00905, we present an efficient algorithm for computing topological intersection numbers of divisors in a broad class of elliptic fibrations with the aid of a symbolic computing tool.

Intersection Homology Betti Numbers [PDF]
Proceedings of the American Mathematical Society, 1995 A generalization of the formula of Fine and Rao for the ranks of the intersection homology groups of a complex algebraic variety is given. The proof uses geometric properties of intersection homology and mixed Hodge theory.

The Intersection Numbers [PDF]
Transactions of the American Mathematical Society, 1923 1. In his first memoir on analysis situst Poincaredefined a number N(Fk, Jin_k) which had previously been considered, at least in special cases, by Kronecker. With certain conventions as to sign this number represents the excess of the number of positive over the number of negative intersections of a k-dimensional circuit Fk with an (n k) -dimensional ...

Local constancy of intersection numbers
Algebra & Number Theory, 2022 We prove that, in certain situations, intersection numbers on formal schemes that come in profinite families vary locally constantly in the parameter. To this end, we define the product $S\times M$ of a profinite set $S$ with a locally noetherian formal scheme $M$ and study intersections thereon.

Open intersection numbers, Kontsevich-Penner model and cut-and-join operators [PDF]
, 2015 We continue our investigation of the Kontsevich--Penner model, which describes intersection theory on moduli spaces both for open and closed curves.

The symmetry of intersection numbers in group theory [PDF]
, 1997 For suitable subgroups of a finitely generated group, we define the intersection number of one subgroup with another subgroup and show that this number is symmetric. We also give an interpretation of this number.Comment: 19 pages.
