    • A wavelet based sparse grid method for the electronic Schrödinger equation 

      Griebel, Michael; Hamaekers, Jan (2006-05)
      We present a direct discretization of the electronic Schrödinger equation. It is based on one-dimensional Meyer wavelets from which we build an anisotropic multiresolution analysis for general particle spaces by a tensor ...

    • Sparse grids for the Schrödinger equation 

      Griebel, Michael; Hamaekers, Jan (2005-12)
      We present a sparse grid/hyperbolic cross discretization for many-particle problems. It involves the tensor product of a one-particle multilevel basis. Subsequent truncation of the associated series expansion then results ...
