Exact axisymmetric Taylor states for shaped plasmas
Antoine J. Cerfon, Michael O'Neil
We present a general construction for exact analytic Taylor states in axisymmetric toroidal geometries. In this construction, the Taylor equilibria are fully determined by specifyi…
Fast symmetric factorization of hierarchical matrices with applications
Sivaram Ambikasaran, Michael O'Neil, Karan Raj Singh
We present a fast direct algorithm for computing symmetric factorizations, i.e. , of symmetric positive-definite hierarchical matrices with weak-admissibility conditions.…
Fast Direct Methods for Gaussian Processes
Sivaram Ambikasaran, Daniel Foreman-Mackey, Leslie Greengard +2
A number of problems in probability and statistics can be addressed using the multivariate normal (Gaussian) distribution. In the one-dimensional case, computing the probability fo…
