We study the nonlinear eigenvalue problem
where , are given constants satisfying , and is a parameter. It is known that under suitable conditions on , is parameterized by the maximum norm of the solution associated with and is a continuous function for . When , and , this equation has been introduced by Chen  as a model equation such that there exist infinitely many solutions near . We prove that is an oscillatory bifurcation curve as by showing the asymptotic formula for . It is found that the shapes of bifurcation curves depend on the condition or . time-map argument and stationary phase method.
