Projection-Based Finite Elements for Nonlinear Function Spaces
Philipp Grohs, Hanne Hardering, Oliver Sander +1
We introduce a novel type of approximation spaces for functions with values in a nonlinear manifold. The discrete functions are constructed by piecewise polynomial interpolation in…
A direct Proof for Quadratic Convergence of the Geometric Newton Method
Markus Sprecher
We consider the problem of numerically computing a critical point of a functional where is a Riemannian manifold. Due to local quadratic convergence a…
A Polynomial-Time Algorithm for the Tridiagonal and Hessenberg P-Matrix Linear Complementarity Problem
Bernd Gärtner, Markus Sprecher
We give a polynomial-time dynamic programming algorithm for solving the linear complementarity problem with tridiagonal or, more generally, Hessenberg P-matrices. We briefly review…
Counting Unique-Sink Orientations
Jan Foniok, Bernd Gärtner, Lorenz Klaus +1
Unique-sink orientations (USOs) are an abstract class of orientations of the n-cube graph. We consider some classes of USOs that are of interest in connection with the linear compl…
