Title: Singular integrals of the time-harmonic relativistic Dirac
       equation on a piecewise Liapunov surface

Author: Baruch Schneider (Izmir Univ. of Economics, Turkey)

Abstract: 
 We give a short proof of a formula of Poincare-Bertrand in the
 setting of time-harmonic solutions of the relativistic Dirac
 equation on a piecewise Liapunov surface, as well as for some
 versions of quaternionic analysis.
