Darboux Integrability and Limit Cycles for a Class of Polynomial Differential Systems,us polynomials of degree .. Inside this class we identify new subclasses of Darboux integrable systems. Moreover, under additional conditions such Darboux integrable systems can have at most three limit cycles. We provide the explicit expression of these limit cycles.清醒 发表于 2025-3-25 14:38:07

,On “Good” Bases of Algebraico-Differential Ideals,d for solving arbitrary systems of algebrico-differential equations. The existence of “good bases” of the associated algebrico-differential ideals is also studied in this way. As an illustration of the method, the Devil problem of Pommaret is studied in detail.Antecedent 发表于 2025-3-26 07:44:27
