IceTop is the surface air shower array above the IceCube [1] neutrino detector. Its primary purpose is to complement the detection of high energy astrophysical neutrinos and support IceCube by identifying background events. To do that IceTop will [2]: 1) Tag a fraction of the small showers on the surface that are associated with the main atmospheric muon background in IceCube. Among the identif...

Preconditioning Legendre Spectral Collocation Approximations to Elliptic Problems

This work deals with the H1 condition numbers and the distribution of the ~ N;Msingular values of the preconditioned operators f~ 1 N;M WN;M ÂN;Mg. ÂN;M is the matrix representation of the Legendre Spectral Collocation discretization of the elliptic operator A de ned by Au := u + a1ux + a2uy + a0u in (the unit square) with boundary conditions: u = 0 on 0; @u @ A = u on 1. ~ N;M is the sti ness ...
