摘要：In this talk, we introduceour recent results on turning point theory of singular perturbed systems, whichcauses stability loss delay phenomena, of singularly perturbed systems. As anapplication of our theory, we study the existence of relaxation oscillation of a modelfrom bioeconomy. The main tools are geometric singular perturbation theoryincluding blow--up techniques.
