Abstract
M.G. Krein’s method of directing mappings is extended to quasidensely defined symmetric operators with selfadjoint definitizable extensions in some Krein space, by direct use of the spectral function of the extension, thus avoiding a reduction to the semidefinite situation.
To Heinz Langer on the occasion of his retirement.
