We establish an inequality of a weight coecient by introducing a parameter λ and using the Euler-Maclaurin expansion. Using this inequality, we derive a reverse of the Hilbert's type inequality. As an applications, an equivalent form is obtained.

Subharmonic periodic solutions of order (1/2 ,1/4) to a weakly second order ordinary differential equation which governed the motion of a micro-dynamical system are studied analytically. Applying the method of multiple scales, we derive the modulation equation in the amplitude an...
