Efficient computation of Riemann–Roch spaces for plane curves with ordinary singularities
We revisit the seminal Brill-Noether algorithm for plane curves with ordinary singularities. Our new approach takes advantage of fast algorithms for polynomials and structured matrices. We design a new probabilistic algorithm of type Las Vegas that computes a Riemann-Roch space in expected sub-quadr...

Summary: | We revisit the seminal Brill-Noether algorithm for plane curves with ordinary singularities. Our new approach takes advantage of fast algorithms for polynomials and structured matrices. We design a new probabilistic algorithm of type Las Vegas that computes a Riemann-Roch space in expected sub-quadratic time. |
