The Chern classes of complete intersection varieties

open access: yes上海师范大学学报. 自然科学版, 2022
The study of inequalities of Chern classes of varieties (also known as the geographical problem of varieties) is an important topic in algebraic geometry.

Heterotic line bundle models on generalized complete intersection Calabi Yau manifolds

open access: yesJournal of High Energy Physics, 2021
The systematic program of heterotic line bundle model building has resulted in a wealth of standard-like models (SLM) for particle physics. In this paper, we continue this work in the setting of generalised Complete Intersection Calabi Yau (gCICY ...

ELLIPTIC GENERA OF COMPLETE INTERSECTIONS [PDF]

open access: yesInternational Journal of Mathematics, 2005
We propose a new definition of the elliptic genera for complete intersections, not necessarily nonsingular, in projective spaces. We also prove they coincide with the expressions obtained from Landau–Ginzburg model by an elementary argument.

Continuité des racines d’après Rabinoff

open access: yesComptes Rendus. Mathématique, 2023
The content of this paper is a generalization of a theorem by Joseph Rabinoff: if $\mathscr{P}$ is a finite family of pointed and rational polyhedra in $N_\mathbb{R}$ such that there exists a fan in $N_\mathbb{R}$ that contains all the recession cones of

On the Stanley Depth of Powers of Monomial Ideals

open access: yesMathematics, 2019
In 1982, Stanley predicted a combinatorial upper bound for the depth of any finitely generated multigraded module over a polynomial ring. The predicted invariant is now called the Stanley depth. Duval et al.

Are complete intersections complete intersections?

open access: yesJournal of Algebra, 2012
A commutative local ring is generally defined to be a complete intersection if its completion is isomorphic to the quotient of a regular local ring by an ideal generated by a regular sequence. It has not previously been determined whether or not such a ring is necessarily itself the quotient of a regular ring by an ideal generated by a regular sequence.

Sound and Complete Typing for lambda-mu [PDF]

open access: yesElectronic Proceedings in Theoretical Computer Science, 2011
In this paper we define intersection and union type assignment for Parigot's calculus lambda-mu. We show that this notion is complete (i.e. closed under subject-expansion), and show also that it is sound (i.e. closed under subject-reduction).

Complete intersections of quadrics and complete intersections on Segre varieties with common specializations

open access: yesDocumenta Mathematica, 2021
We investigate whether surfaces that are complete intersections of quadrics and complete intersection surfaces in the Segre embedded product \mathbf{P}^1\times \mathbf{P}^k\hookrightarrow \mathbf{P}^{2k+1} can belong to the same Hilbert scheme. For
