摘要我们修改了Mayr和Meyer的例子,给出了一个由二次型生成的多项式理想的例子,它表现出理想成员问题的双指数增长。我们还表明,均匀化的这个例子给出了一组元素,其中有一个最小的合点的双指数度。
Abstract 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 exponential degree.
