We study the Dirichlet problem for discrete harmonic functions in unbounded product domains on multidimensional lattices. First we prove some versions of the Phragmén-Lindelöf theorem and use Fourier ...

The conditioning of spline collocation matrices is considered in the case of a boundary value problem for an mth order equation. For bases with continuity built in (which corresponds to most current ...

The evolution of complex families of related activities is a common aspect of mammalian organisms. Functions that might be mediated by a single activity in Drosophila or Caenorhabditis elegans are ...
