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 ...

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

Complete integration-by-parts reductions of the non-planar hexagon-box via module intersections
We present the powerful module-intersection integration-by-parts (IBP) method, suitable for multi-loop and multi-scale Feynman integral reduction.

Quasi-complete intersections in P2 and syzygies [PDF]
Let C \in P2 be a reduced, singular curve of degree d and equation f = 0. Let \Sigma denote the jacobian subscheme of C. We have 0 -> E -> 3.O -> I_\Sigma(d-1) -> 0 (the surjection is given by the partials of f).

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 ...

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 intersections: Moduli, Torelli, and good reduction [PDF]
We study the arithmetic of complete intersections in projective space over number fields. Our main results include arithmetic Torelli theorems and versions of the Shafarevich conjecture, as proved for curves and abelian varieties by Faltings. For example,

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.

The reaction trajectories of photoexcited molecules may involve transitions through conical intersections, which are ubiquitous in nature but challenging to characterize.
