On the crossing limit cycles created by a discontinuous piecewise differential system formed by three linear Hamiltonian saddles
We study planar discontinuous piecewise differential systems formed by three linear Hamiltonian saddles separated by the non-regular line Σ={(x,y)∈R2:(y=0)∨(x=0∧y≥0)}. We prove that when the linear...
