• Periodic action functional
• Lagrangian and Hamiltonian formalisms
• Time-dependent harmonic oscillators

I discuss the problem of time-dependent harmonic oscillators on the basis of a periodic functional approach to the calculus of variations. Both the Lagrangian and Hamiltonian formulations are explored and discussed in some detail. Some interesting consequences are revealed.
