Fast computation of a Groebner basis. What is possible?

Assume for simplicity that your polynomials are homogeneous of degree three. If you have a complete intersection, it has Hilbert series $$ (1-t^3)^{18}/(1-t)^{19} = (1+t+t^2)^{18}/(1-t) $$ It is conc …

Dimension of a homogeneous polynomial system

I don't have a complete solution, but the following may be helpful. Change variables by $z_i = \sum_j y_j \xi^{ij}$ where $\xi$ is $m$-th primitive root of $1$. Then the first line equations (I am us …
