Let K be a field and (f1, ..., fn)\subset K[X1, ..., Xn] be a sequence of quasi-homogeneous polynomials of respective weighted degrees (d1, ..., dn) w.r.t a system of weights (w1,...,wn). Such systems are likely to arise from a lot of applications, including physics or cryptography. We design strategies for computing Gröbner bases for quasi-homogeneous systems by adapting existing algorithms for homogeneous systems to the quasi-homogeneous case. Overall, under genericity assumptions, we show that for a generic zero-dimensional quasi homogeneous system, the complexity of the full strategy is polynomial in the weighted Bézout bound Π_{i=1n}di / Π_{i=1nwi. We provide some experimental results based on generic systems as well as systems arising from a cryptography problem. They show that taking advantage of the quasi-homogeneous structure of the systems allow us to solve systems that were out of reach otherwise. |
