Abstract: Let be a -periodic potential such that . The classical Lyapunov criterion to stability of Hill's equation is , where is the negative part of . In this paper, we will use a relation between the (anti-)periodic and the Dirichlet eigenvalues to establish some lower bounds for the first anti-periodic eigenvalue. As a result, we will find the best Lyapunov-type stability criterion using norms of , . The numerical simulation to Mathieu's equation shows that the new criterion approximates the first stability region very well.
