    Description / Table of Contents: Zusammenfassung In dieser Arbeit wurden zwei Methoden für die numerische Bestimmung von zwei-oder dreidimensionalen Cauchy-Hauptwert-Integralen eingeführt. Diese Integrale wurden entweder über eine flache Lyapounov-Schale oder ein geschlossenes Lyapunov-Gebiet definiert. Eine Gaußsche Quadraturformel, die das Konzept der finiten Integrale benutzt, wurde für die Bestimmung dieser Integrale gebildet. Um die Resultate zu veranschaulichen wurden verschiedene numerische und theoretische Anwendungen gegeben.
    Notes: Summary In the present paper two techniques are introduced for the numerical evaluation of either two-, or three-dimensional Cauchy principal-value integrals defined either over a shallow Lyapunov shell, or a closed Lyapunov domain respectively. A Gaussian cubature formula was established for the evaluation of these integrals which makes use of the concept of the finite-part integrals. Several numerical and theoretical applications are given to illustrate the results.
