Note on singular Sturm comparison theorem and strict majorant condition
In this note, the authors establish a singular Sturm comparison theorem for two linear Hamiltonian systems satisfying a standard majorant condition and the normality assumption. Both endpoints of the considered interval may be singular. The presented result extends some previous Sturm comparison theorems for linear Hamiltonian systems.
