In this paper, we study the unilateral global bifurcation from infinity in nonlinearizable eigenvalue problems for the one-dimensional Dirac equation. We show the existence of two families of unbounded continua of the set of nontrivial solutions emanating from asymptotically bifurcation intervals and having the usual nodal properties near these intervals.

Symmetry Breaking Bifurcation

We show the existence of a symmetry-breaking bifurcation point for the one-dimensional Hénon equation [Formula: see text] where [Formula: see text] and [Formula: see text]. Moreover, employing a variant of Rabinowitz’s global bifurcation, we obtain the unbounded connected set (the first of the alternatives about Rabinowitz’s global bifurcation), which emanates from the symmetry-breaking bifurcation point. Finally, we give an example of a bounded branch connecting two symmetry-breaking bifurcation points (the second of the alternatives about Rabinowitz’s global bifurcation) for the problem [Formula: see text] where [Formula: see text] is a specified continuous parametrization function.

We consider the equations involving the one-dimensional p-Laplacian (P):  (u′tp-2u′(t))′+λf(u(t))=0, 0<t<1, and u(0)=u(1)=0, where p>1,λ>0,f∈C1(R;R),f(s)s>0, and s≠0. We show the existence of sign-changing solutions under the assumptions f∞=lim|s|→∞⁡(fs/sp-1)=+∞ and f0=lim|s|→0(f(s)/sp-1)∈[0,∞]. We also show that (P) has exactly one solution having specified nodal properties for λ∈(0,λ*) for some λ*∈(0,∞). Our main results are based on quadrature method.
