Purpose: Study the existence of inertial manifolds and the asymptotic behavior of solutions to certain classes of evolution equations in an infinite-dimensional Banach space. The evolution equations considered with the linear parts is the generator of a semigroup and the Lipschitz coefficient of the nonlinear term may depend on time and belongs to admissible function spaces which contain wide classes of function spaces like Lp-spaces, the Lorentz spaces Lp,q and many other function spaces occurring in interpolation theory.

The set of intracavity field equations describing the evolution of intra-cavity pumping, Stokes and anti-Stokes powers of Raman laser is presented. Most attention is given to intra-cavity competition of two Raman waves, which depends on cavity properties, frequency shift and phase mismatch. The calculated results are based on Ge-doped and D2-gas-in glass fiber lasers at CW-regime and pulse-pumped regime.

MODELLING AIDS EPIDEMIC AND TREATMENT WITH DIFFERENCE EQUATIONS K. M. TAMIZHMANI, A. RAMANI, B. GRAMMATICOS, AND A. S. CARSTEA Received 15 October 2003 and in revised form 10 March 2004 We propose two models for the description of the dynamics of an AIDS epidemic and of the effect of a combined-drugs AIDS treatment based on difference equations. We show that our interacting population model, despite its extreme simplicity, describes adequately the evolution of an AIDS epidemic. A cellular-automaton analogue of the discrete system of equations is presented as well.

Planarization method s if the graph is nonplanar, make it planar! (by placing dummy vertices at the crossings) s use one of the drawing algorithms for planar graphs e.g., GIOTTO [Tamassia Batini Di Battista 87] Orientation method s orient the graph into a digraph s use one the drawing algorithms for digraphs Force-Directed method s define a system of forces acting on the vertices and edges s find a minimum energy state (solve differential equations or simulate the evolution of the system)
