Center node: "a fast algorithm for computing the p curvature"
  Abstract: We design an algorithm for computing the p-curvature of a differential system in positive characteristic p. For a system of dimension r with coefficients of degree at most d, its complexity is O~ (p d rω) operations in the ground field (where ω denotes the exponent of matrix multiplication), whereas the size of the output is about p d r2. Our algorithm is then quasi-optimal assuming that matrix multiplication is (i.e. ω = 2). The main theoretical input we are using is the existence of a well-suited ring of series with divided powers for which an analogue of the Cauchy--Lipschitz Theorem holds.

Connected through hyperedge HE-1 (induced by source paper "computation of the similarity class of the p curvature"):
  with members:
    - "a fast algorithm for computing the characteristic polynomial of the p curvature"
    - "powers of tensors and fast matrix multiplication"
    - "faster polynomial multiplication over finite fields"
    - "fast algorithms for differential equations in positive characteristic"
