Abstract

The classical moment problem for continued fraction expansion of relaxation functions is surveyed. The theory is then extended to the moment problem associated to relaxation operators or super-operators. Numerical aspects and sensitivity of algorithms to round-off errors are also examined. A new convenient approach is developed exploiting a product-difference recursive scheme, within the memory function formalism.
