A Roe-type Riemann solver based on the spectral decomposition of the equations of Relativistic Magnetohydrodynamics
Roe-type Riemann solver spectral decomposition equations of Relativistic Magnetohydrodynamics
2011/3/2
In a recent paper (Ant´on et al. 2010) we have derived sets of right and left eigenvectors of the Jacobians of the relativistic MHD equations, which are regular and span a complete basis in any ...
Supersymmetric heterotic string models, built from a Calabi-Yau threefold X endowed with a stable vector bundle V , usually start from a phenomenologically motivated choice of a bundle Vv in the visib...
An Inverse Power Method for Nonlinear Eigenproblems with Applications in 1-Spectral Clustering and Sparse PCA
Inverse Power Method Nonlinear Eigenproblems
2011/1/4
Many problems in machine learning and statistics can be formulated as (generalized) eigenproblems. In terms of the associated optimization problem, computing linear eigenvectors amounts to finding cri...

For a bounded planar domain $\Omega^0$ whose boundary contains a number of flat pieces $\Gamma_i$ we consider a family of non-symmetric billiards $\Omega$ constructed by patching several copies of $\O...
