Abstract

We give a structural theorem for ℚ-factorial toric varieties covered by lines in ℙN, and compute their dual defect. This yields a characterization of defective ℚ-factorial toric varieties in ℙN. The combinatorial description of such varieties is used to characterize some finite sets of monomials with discriminant equal to one.
