Understanding extreme events attracts scientists due to substantial impacts. In this work, we study the emergence of extreme events in a fractional system derived from a Liénard-type oscillator. The effect of fractional-order derivative on the extreme events has been investigated for both commensurate and incommensurate fractional orders. Especially, such a system displays multistability and coexistence of multiple extreme events.

具有极端事件的分数系统中的混沌

由于重大影响，了解极端事件吸引了科学家。在这项工作中，我们研究了从 Liénard 型振荡器派生的分数系统中极端事件的出现。分数阶导数对极端事件的影响已针对相称和不相称的分数阶进行了研究。特别是，这样的系统表现出多重稳定性和多个极端事件的共存。
