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 modify the example of Mayr and Meyer to give an example of a polynomial ideal generated by quadrics which exhibits double exponential growth for the ideal membership problem. We also show that the homogenization of this example gives a set of elements which has a minimal syzygy of double exponent

This note describes ideals generated by symmetric polynomials in two sets of variables A, B. These ideals generalize the ideals generated by differences of elementary symmetric functions considered by and the ideals generated by symmetric functions in the formal difference A-B described by . The ma
