Global bifurcation from infinity of non-trivial solutions of asymptotic linear eigenvalue problems for ordinary differential equations of the second and fourth order in which the boundary condition includes a spectral parameter was studied in the articles. The existence of a pair of families of global continuums branching from the asymptotic bifurcation points of the non-trivial solutions of each of these problems and located in classes with oscillatory properties of the eigenfunctions of the corresponding linear problems and their derivatives around those points is proved.
