H2\mathcal{H}^2-matrices for translation-invariant kernel functions

By Steffen Börm and Janne Henningsen
Boundary element methods for elliptic partial differential equations typically lead to boundary integral operators with translation-invariant kernel functions. Taking advantage of this property is fairly simple for particle methods, e.g., Nystrom-type discretizations, but more challenging if the supports of basis functions have to be taken into account.
