 Using Galerkin s method and modified potential well theory, we prove that if M(r) and α satisfy some conditions and initial value is small enough, there exists a unique global solution.

Synthetic permeability prediction for lead-zinc sintering process based on the improved gray theory

The ensuring years saw much discussion of whether nature was more like Einstein\'s special relativity(SR) or modified-theory of Lorentz(MOL),the principal differences between the two relativity theories stem from the equivalence of all inertial frames in SR,and the existence of a preferred frame in MOL.
