Abstract
We investigate a two‐dimensional differential system of the form x' = f(t, y), y' = h(t, x) together with the boundary conditions x(0) = 0, x(1) = 0 by using the quasilinearization process. We show that if this problem allows for quasilinearization with respect to essentially different linear parts, then it has multiple solutions.
