Toric 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...
متن کاملSome Properties of Complete Intersections in "good" Projective Varieties
In [10] it was proved that, if X denotes a non singular surface which is a complete intersection in P£ (k an algebraically closed field of characteristic 0) and C an irreducible curve on X, which is a set-theoretic complete intersection in X, then C is actually a complete intersection in X the key point was to show that Pic (X) modulo the subgroup generated by the class of Θx(l) is torsion-free...
متن کاملThe Genus 0 Gromov-Witten Invariants of Projective Complete Intersections
We describe the structure of mirror formulas for genus 0 Gromov-Witten invariants of projective complete intersections with any number of marked points and provide an explicit algorithm for obtaining the relevant structure coefficients. As an application, we give explicit closed formulas for the genus 0 Gromov-Witten invariants of Calabi-Yau complete intersections with 3 and 4 constraints. The ...
متن کاملInfinite-dimensional Complex Projective Spaces and Complete Intersections
Let V be an infinite-dimensional complex Banach space and X ⊂ P(V ) a closed analytic subset with finite codimension. We give a condition on X which implies that X is a complete intersection. We conjecture that the result should be true for more general topological vector spaces.
متن کاملLocalization computation of one-point disk invariants of projective Calabi-Yau complete intersections
We define one-point disk invariants of a smooth projective Calabi-Yau (CY) complete intersection (CI) in the presence of an anti-holomorphic involution via localization. We show that these invariants are rational numbers and obtain a formula for them which confirms, in particular, a conjecture by Jinzenji-Shimizu [JS, Conjecture 1]. 1 The one-point disk mirror theorem The problem of defining an...
