Complete intersections in binomial and lattice ideals [PDF]
For the family of graded lattice ideals of dimension 1, we establish a complete intersection criterion in algebraic and geometric terms. In positive characteristic, it is shown that all ideals of this family are binomial set theoretic complete ...

Calabi-Yau generalized complete intersections and aspects of cohomology of sheaves
We consider generalized complete intersection manifolds in the product space of projective spaces, and work out useful aspects pertaining to the cohomology of sheaves over them.

Choice of the control variables of an isolated intersection by graph colouring [PDF]
This paper deals with the problem of grouping the traffic streams into some groups - signal groups on a signalized intersection. The fact that more traffic streams, which are not in a conflict, can be controlled by one sequence of traffic lights

Set-theoretic complete intersections [PDF]
In this article we establish that: (1) Every monomial curve in P k n {\mathbf {P}}_k^n is a set-theoretic complete intersection, where k k is a field of characteristic p p (and thus generalize a result of R. Hartshorne [3]). (2) Let

The $4n^2$-inequality for complete intersection singularities [PDF]
The famous $4n^2$-inequality is extended to generic complete intersection singularities: it is shown that the multiplicity of the self-intersection of a mobile linear system with a maximal singularity is higher than $4n^2\mu$, where $\mu$ is the ...

Complete intersections in P^2 through separating sequences
In this paper we characterize the finite sets of points in P2, arising as a complete intersection of two curves, by means of their realizable sequences. Actually, we show that a reduced 0-dimensional scheme in P2 is a complete intersection of type (a, b)

Complete intersection dimension [PDF]
Let \(A\) be a Noetherian local ring and \(M\) a finitely generated \(A\)-module. In the case where \(\text{pd}_A M < \infty\), the structure of \(M\) is very rigid but we know a little bit if \(\text{pd}_A M = \infty\). In the present paper, the authors define a new invariant of \(M\), called the complete intersection dimension \(\text{CI-dim}_A M ...

A Classiffier for Unimodular Isolated Complete Intersection Space Curve Singularities
C.T.C. Wall classified the unimodular complete intersection singularities. He indicated in the list only the μ-constant strata and not the complete classification in each case.

Complete intersection lattice ideals
In this paper we completely characterize lattice ideals that are complete intersections or equivalently complete intersections finitely generated semigroups of $\bz^n\oplus T$ with no invertible elements, where $T$ is a finite abelian group. We also characterize the lattice ideals that are set-theoretic complete intersections on binomials.
