SET-THEORETIC COMPLETE INTERSECTIONS IN CHARACTERISTIC p
We describe a class of toric varieties which are set-theoretic complete intersections only over fields of one positive characteristic p.
متن کاملOn toric varieties which are almost set-theoretic complete intersections
We describe a class of affine toric varieties V that are set-theoretically minimally defined by codimV + 1 binomial equations over fields of any characteristic.
متن کاملAlmost set-theoretic complete intersections in characteristic zero
We present a class of toric varieties V which, over any algebraically closed field of characteristic zero, are defined by codim V +1 binomial equations .
متن کاملOn Binomial Set-Theoretic Complete Intersections in Characteristic p
Using arithmetic conditions on affine semigroups we prove that for a simplicial toric variety of codimension 2 the property of being a set-theoretic complete intersection on binomials in characteristic p holds either for all primes p, or for no prime p, or for exactly one prime p.
متن کاملThe Stanley-Reisner ideals of polygons as set-theoretic complete intersections
We show that the Stanley-Reisner ideal of the one-dimensional simplicial complex whose diagram is an n-gon is always a set-theoretic complete intersection in any positive characteristic.
