Kurzfassung englisch:
H-matrices have recently been introduced for the efficient numerical
treatment of fully populated matrices which arise, e.g., in the
numerical treatment of integral equations.
In our talk, we first give a short introduction to H-matrices
- including uniform H-matrices and H^2-matrices - and discuss
complexity of related algorithms, e.g. LU decomposition and
matrix-vector-multiplication, and storage requirements. For
assembling an H-matrix approximation of the Galerkin stiffness matrix
of an integral equation, we use interpolation of the integral kernel
in the so-called far field.
Second, we present some analytical results from a joint work with
Nikola Popovic on the applicability of H-matrix techniques for the
numerical computation of the stray-field in micromagnetics.
Numerical experiments conclude the talk.
