\(\mathcal H\)-matrix approximation for elliptic solution operators in cylinder domains (English)
0 references
A data-sparse and accurate approximation of the normalized hyperbolic operator sine family, generated by a strongly positive elliptic operator, is developed. As an application, the data-sparse factorized representation of the Poincaré-Steklov operators associated with elliptic problems in tube domains is considered.
