Rational curves in CICY's in products of two projective spaces

Algebraic Geometry 2016-03-03 v1

Abstract

Let XX be the product of two projective spaces and consider the general CICY threefold YY in XX with configuration matrix AA. We prove the finiteness part of the analogue of the Clemens' conjecture for such a CICY in low bidegrees. More precisely, we prove that the number of smooth rational curves on YY with low bidegree and with nondegenerate birational projection is at most finite (even in cases in which positive dimensional families of degenerate rational curves are known).
