\n Abstract:<\/span>
\n Kinetic equations have uncertain inputs, such as the scattering kernels, initial or boundary data.
\nIn this talk we will study the generalized polynomial chaos (gPC) approach to\u00a0such kinetic equations with multiple time or space scales, <\/span>and\u00a0show that they can be made asymptotic-preserving, in the sense\u00a0that the gPC scheme preserves various asymptotic limits in the discrete space.
\nThis allows the implemention of the gPC methods for these problems without numerically resolving (by space,\u00a0time, and gPC modes) the small scales. We also give a fast gPC algorithm for\u00a0the Boltzmann equation\u00a0with uncertainties in its collision kernel, initial or boundary data.<\/span><\/p>\n","protected":false},"excerpt":{"rendered":"
