Abstract

Description

We describe classes of toric varieties of codimension 2 which are either minimally defined by 3 binomial equations over any algebraically closed field, or are set-theoretic complete intersections in exactly one positive characteristic.
Revised version. To appear in: Rendiconti dell'Istituto di Matematica dell'Universita' di Trieste. Dedicated to the memory of Fabio Rossi
