# Infinitely many solutions to superquadratic planar Dirac-type systems

• It is proved the existence of infinitely many solutions to a superquadratic Dirac-type boundary value problem of the form $\tau z = \nabla_z F(t,z)$, $y(0) = y(\pi) = 0$ ($z=(x,y)\in \mathbb{R}^2$). Solutions are distinguished by using the concept of rotation number. The proof is performed by a global bifurcation technique.
