Resumen de Planar Dirac-type systems: the eigenvalue problem and a global bifurcation result

Anna Capietto, Walter Dambrosio

• We deal with a boundary value problem on the half-line for planar systems of Dirac type. We first study the eigenvalue problem in the linear case and define an index for nontrivial solutions.

  We then give a global bifurcation result for nonlinear problems.
