报告题目：Snakes and Isolas of Localized Patterns

报告摘要：As we know, there are many systems undergoing different kinds of snaking bifurcations, such as slanted snaking, collapsed snaking etc., and isola bifurcations including a stack of isolas and a nested of isolas. In this talk, we will focus on the existence of snakes and isolas of a non-symmetric system. Conditions are derived that guarantee snaking or result in diagrams that either consist entirely of isolas.
