Binomial Difference Ideals
In this paper, binomial difference ideals are studied. Three canonical representations for Laurent binomial difference ideals are given in terms of the reduced Gröbner basis of Z[x]-lattices, regular and coherent difference ascending chains, and partial characters over Z[x]-lattices, respectively. Criteria for a Laurent binomial difference ideal to be reflexive, prime, well-mixed, and perfect a...
متن کاملBinomial Ideals
We investigate the structure of ideals generated by binomials (polynomials with at most two terms) and the schemes and varieties associated to them. The class of binomial ideals contains many classical examples from algebraic geometry, and it has numerous applications within and beyond pure mathematics. The ideals defining toric varieties are precisely the binomial prime ideals. Our main result...
متن کاملCellular Binomial Ideals. Primary Decomposition of Binomial Ideals
It is known that algorithms exist which compute primary decompositions of polynomial ideals (Gianni et al., 1988; Eisenbud et al., 1992; Becker and Weispfenning, 1993; and more recently Shimoyama and Yokoyama, 1996). However, in case the ideal is binomial, binomiality of its primary components is not assured, that is, the above algorithms do not necessarily compute a decomposition into binomial...
متن کاملBinomial vanishing ideals
In this note we characterize, in algebraic and geometric terms, when a graded vanishing ideal is generated by binomials over any field K. 2010 MSC: 13F20, 13C05, 14H45
متن کاملDecompositions of Binomial Ideals
A binomial ideal in a polynomial ring is an ideal which can be generated by binomials. We present Binomials, a package for the computer algebra system Macaulay 2 (Eisenbud et al (2001)), which specializes well known algorithms to binomial ideals, allowing for a significant speedup of common computations like primary decomposition. Central parts of the implemented algorithms go back to the found...
