Abstract: The initial-regular oblique derivative problem for nonlinear parabolic systems of several second order complex equations with measurable coefficients in a multiply connected domain is discussed. Firstly, the author is a priori estimates of solutions for the above initial-boundary value problem with some conditions, afterwards by using the above estimates of solutions and the method of parameter extension, the existence of solutions for the above problem is proved.

Key words: initial-regular oblique derivative problems, nonlinear parabolic systems, measurable coefficients
