Abstract
This article is concerned with the limit-point case (l.p.c.) of a Hamiltonian system. We present new proofs for several existing equivalent conditions on the l.p.c. established in terms of the asymptotic behaviour of the square integrable solutions of Hamiltonian systems with different spectral parameters and functions in the domain of the corresponding maximal operator, respectively. Further, we give two equivalent conditions in terms of the asymptotic behaviour of the square integrable solutions of Hamiltonian systems with the same complex and real spectral parameters, respectively. In addition, we establish two limit-point criteria which extend the relevant existing results.
