Abstract : Under this grant the researchers have investigated: (1) Laser instabilities, (2) Singular bifurcation to relaxation oscillations, (3) Slow passage through bifurcation points, (4) Propagation failure in discrete reaction-diffusion equations, (5) Large coherent fluid structures in boundary layers, (6) Primary and secondary flutter in flexible channel flows, (7) Energy leakage and reflection in slowly varying wave-guides, (8) Pulse dynamics in nonlinear optical fibers and switches and (9) Numerical modeling of optical pulse propagation.
