Trivariate Monomial Complete Intersections and Plane Partitions
We consider the homogeneous components Ur of the map on R = k[x, y, z]/(xA, yB , zC) that multiplies by x + y + z. We prove a relationship between the Smith normal forms of submatrices of an arbitrary Toeplitz matrix using Schur polynomials, and use this to give a relationship between Smith normal form entries of Ur. We also give a bijective proof of an identity proven by J. Li and F. Zanello e...
متن کامل0 On two simple criteria for recognizing complete intersections in codimension 2
Developing a previous idea of Faltings, we characterize the complete intersections of codimension 2 in P n , n ≥ 3, over an algebraically closed field of any characteristic, among l.c.i. X, as those that are subcanonical and scheme-theoretically defined by p ≤ n − 1 equations. Moreover we give some other results assuming that X is smooth and a numerical complete intersection, p ≤ n and the char...
متن کاملEliminating Higher-Multiplicity Intersections, III. Codimension 2
We study conditions under which a finite simplicial complex K can be mapped to R without higher-multiplicity intersections. An almost r-embedding is a map f : K → R such that the images of any r pairwise disjoint simplices of K do not have a common point. We show that if r is not a prime power and d ≥ 2r + 1, then there is a counterexample to the topological Tverberg conjecture, i.e., there is ...

متن کاملToric complete intersections and weighted projective space
It has been shown by Batyrev and Borisov that nef partitions of reflexive polyhedra can be used to construct mirror pairs of complete intersection Calabi–Yau manifolds in toric ambient spaces. We construct a number of such spaces and compute their cohomological data. We also discuss the relation of our results to complete intersections in weighted projective spaces and try to recover them as sp...
