Abstract: | We consider two classes of systems of partial differential equations of first order. One consists of generalized Stokes-Beltrami equations $ Aw_z = w^*_z $ , $ lambda Bw_{bar z} -w^*_{bar z} $ with square matrices A and B and a scalar factor u . The other may be written in matrix notation as $ v_{bar z} = c{bar v} $ where c denotes a square matrix. This system is known as a Pascali system. Both systems are in close connections to certain systems of second order for which the solutions can be represented using particular differential operators. On the basis of these relations we give the solutions of the first order systems explicitly. |
