Are complete intersections complete intersections?

Journal 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.

Noncommutative complete intersections

Journal of Algebra, 2015
Several generalizations of a commutative ring that is a graded complete intersection are proposed for a noncommutative graded $k$-algebra; these notions are justified by examples from noncommutative invariant theory.

ELLIPTIC GENERA OF COMPLETE INTERSECTIONS [PDF]

International 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.

Assisting Drivers at Stop Signs in a Connected Vehicle Environment

Future Internet, 2023
Road intersections are shared among several conflicted traffic flows. Stop signs are used to control competing traffic flows at road intersections safely.

Monomial Curves in Afinne Space and their Associated Prime Ideals with Six Generators as Set-Theoretic Complete Intersections

Communications, 2014
The paper deals with the problem of the expression of associated prime ideals of monomial curves in the affine space A4 as set-theoretic complete intersections.

Quiver theories and Hilbert series of classical Slodowy intersections

Nuclear Physics B, 2020
We build on previous studies of the Higgs and Coulomb branches of SUSY quiver theories having 8 supercharges, including 3dN=4, and Classical gauge groups. The vacuum moduli spaces of many such theories can be parameterised by pairs of nilpotent orbits of

Moduli spaces of Calabi–Yau complete intersections

Nuclear Physics B, 2015
In this short note, based on the work [7] in 1994, we describe compactifications of moduli spaces of Calabi–Yau complete intersections in Gorenstein toric Fano varieties.

SET-THEORETIC COMPLETE INTERSECTIONS ON BINOMIALS, THE SIMPLICIAL TORIC CASE

Pesquimat, 2014
Let V be a simplicial toric variety of codimension r over a field of any characteristic. We completely characterize the implicial toric varieties that are set-theoretic complete intersections on binomials. In particular we prove that: 1.

Research on the effectiveness of a intersection risk warning system based on driving simulation experiment

Scientific Reports, 2022
In order to improve the traffic safety condition of intersections, a real-time traffic conflict risk warning system (RTCRWS) is proposed for uncontrolled intersections.

On the Variety of Paths on Complete Intersections in Grassmannians

Моделирование и анализ информационных систем, 2014
In this article we study the Fano variety of lines on the complete intersection of the grassmannian G(n, 2n) with hypersurfaces of degrees d1 ..., di . A length l path on such a variety is a connected curve composed of l lines.
