- I have made a little programm for computing puiseux expansions. It can
- still be improved something, but that would only be useful if it is faster
- than the traditional Newton method.
-
- Does anybody out there have an implementation for puiseux expansions. I
- would be very curious about the computertime it takes for a number of
- examples. eg the polynomial over C[x]:
- (y-1)^8+x*(x^2+x+1)^7*(y-1)+(x^2+x+1)^6
-
- Give for instance an expansion for x=RootOf(x^2+x+1), and give the expansion
- modulo x^5. My algorithm needs a few minutes for this.
