报告摘要：The talk will present two oscillation phenomena in multi-scale (singular perturbation) systems, one concerns relaxation oscillations in planar systems of predator-prey type and the other one concerns transient oscillations in a three-dimensional, reversible Latka-Volterra system.  For the first type of oscillations, possible degeneracy of the discriminant function is taken into account and criteria for the existence, uniqueness, and stability of relaxation oscillations will be presented. For the second type of oscillations, a pattern of multiple transient oscillations will be shown. Applications to relaxation oscillations in diffusive PDE systems and transient oscillations in bio-chemical reactions will be discussed.
