Relaxation and asymptotic expansion of controlled stiff differential equations
The control of relaxation-type systems of ordinary differential equations is investigated using the Hamilton-Jacobi-Bellman equation. First, we recast the model as a singularly perturbed dynamics which we embed in a family of controlled systems. Then we study this dynamics together with the value function of the associated optimal control problem.

The discrete (G′/G)-expansion method applied to the differential-difference Burgers equation and the relativistic Toda lattice system [PDF]
We introduce the discrete (G′/G)-expansion method for solving nonlinear differential-difference equations (NDDEs). As illustrative examples, we consider the differential-difference Burgers equation and the relativistic Toda lattice system.

Asymptotic expansions in a nonhomogeneous differential equation [PDF]
In recent papers [2]-[8] asymptotic behavior of the solutions of an ordinary differential equation has been discussed by the development of an asymptotic expansion for the solution that is valid to one term. In [5], [7], asymptotic expansions valid to two terms were obtained for certain solutions of a differential equation.
