half-linear differential equation; conjugacy criteria; variational principle; energy functional; half-linear trigonometric functions
Summary:
We establish new conjugacy criteria for half-linear second order differential equations. These criteria are based on the relationship between conjugacy of the investigated equation and nonpositivity of the associated energy functional.
