We study the reducibility of a linear Schrodinger equation subject to small unbounded almost periodic perturbation which is analytic in time and space. Under appropriate assumptions on smalln...

in this work, the (100) surface of au and pts face centered cubic lattice, has been simulated in monte-carlo method, using a 486-dx2 computer. the potential equation that was used for the interaction among atoms in the metal surfaces is called sutton and chen potential. this potential is introduced for the interaction of floating nuclei in the electron sea, and attractive term is a many body po...

Here, Adomian decomposition method has been used for finding approximateand numerical solutions of nonlinear differential difference equations arising inmathematical physics. Two models of special interest in physics, namely, theHybrid nonlinear differential difference equation and Relativistic Toda couplednonlinear differential-difference equation are chosen to illustrate the validity andthe g...

An analytical equation of state was applied to calculate the thermodynamic properties for argon.The equation of state is that of Song and Mason. It is based on a statistical-mechanical perturbationtheory of the hard convex bodies and can be written as fifth-order polynomial in the density. Thereexist three temperature-dependent parameters: the second virial coefficient, an effective molecularvo...
