1986 Transactions of the American Mathematical Society  
This paper considers the system of nonlinear Dirichlet boundary value problems Here L is a strongly, uniformly elliptic linear partial differential operator, A, p. are real parameters, and /, g: R2 -> R are smooth with /(0,0) = 0 = 9(0,0). A detailed analysis of the solution set to the system is given from the point of view of several parameter bifurcation theory.
