    Der Autor untersucht das asymptotische Verhalten für \(\beta\) \(\downarrow 0\) der Lösung u des Problems \[ \partial u/\partial x-(1- \rho)^ 2a(\rho,x)\partial^ 2u/\partial \rho^ 2+(1- \rho)b(\rho,x)\partial u/\partial \rho +c(\rho,x)\quad u+\beta (d(\rho,x)\partial u/\partial \rho +h(\rho,x)u)=f(\rho,x),0<\rho <1,\quad x>0. \]
