A measure concentration effect for matrices of high, higher, and even higher dimension

Harry Yserentant

Let $n > m$ , and let $A$ be an $(m \times n)$ -matrix of full rank. Then obviously the estimate $∥ A x ∥ \leq ∥ A ∥∥ x ∥$ holds for the euclidean norm of $x$ and $A x$ and the spectral nor…

Numerical Homogenization of Fractal Interface Problems

Ralf Kornhuber, Joscha Podlesny, Harry Yserentant

We consider the numerical homogenization of a class of fractal elliptic interface problems inspired by related mechanical contact problems from the geosciences. A particular featur…
