A combinatorial criterion for the toric ideal arising from a finite graph to be generated by quadratic binomials is studied. Such a criterion guarantees that every Koszul algebra generated by squarefree quadratic monomials is normal. We present an example of a normal non-Koszul squarefree semigroup

We study the primary decomposition of lattice basis ideals. These ideals are binomial ideals with generators given by the elements of a basis of a saturated integer lattice. We show that the minimal primes of such an ideal are completely determined by the sign pattern of the basis elements, while th
Let K be an infinite perfect computable field and let I ⊆ K[x] be a zero-dimensional ideal represented by a Gröbner basis. We derive a new algorithm for computing the reduced primary decomposition of I using only standard linear algebra and univariate polynomial factorization techniques. In practice
monomial idea so I is generated by elements of the form x иии x , where each 1 d . Ž . e is a nonnegative integer . The main results of this paper: a establish a practical i Ž . formula which computes the monomial length of I when Rad I s ŽŽ . . Ž . Rad x , . . . , x R ; b determine necessary and su
It is known that the reduced Gröbner basis of general polynomial ideals can be computed in exponential space. The algorithm, obtained by Kühnle and Mayr, is, however, based on rather complex parallel computations, and, above that, makes extensive use of the parallel computation thesis. In this paper
We present an algorithm that computes an unmixed-dimensional decomposition of a finitely generated perfect differential ideal I. Each I i in the decomposition I = I 1 ∩ • • • ∩ I k is given by its characteristic set. This decomposition is a generalization of the differential case of Kalkbrener's dec
