Low rank differential equations for hamiltonian matrix nearness problems
[OWP-2013-01] (Mathematisches Forschungsinstitut Oberwolfach, 2013-02-08)For a Hamiltonian matrix with purely imaginary eigenvalues, we aim to determine the nearest Hamiltonian matrix such that so me or all eigenvalues leave the imaginary axis. Conversely, for a Hamiltonian matrix with all ... -
Mesh Ratios for Best-Packing and Limits of Minimal Energy Configurations
[OWP-2013-13] (Mathematisches Forschungsinstitut Oberwolfach, 2013-06-10)For $N$-point best-packing configurations $\omega_N$ on a compact metric space $(A, \rho)$, we obtain estimates for the mesh-separation ratio $\gamma(\rho_N , A)$, which is the quotient of the covering radius of $\omega_N$ ... -
Non-stationary multivariate subdivision: joint spectral radius and asymptotic similarity
[OWP-2013-20] (Mathematisches Forschungsinstitut Oberwolfach, 2013-10-29)In this paper we study scalar multivariate non-stationary subdivision schemes with a general integer dilation matrix. We present a new numerically efficient method for checking convergence and Hölder ...
