In particular, precise estimation of feeding rates in

Wei Tang, Da XuIn this article, a direct method for the numerical solution of multi-term fractional differential equations is proposed. The method is based on transforming the original equation into an equivalent system of multi-order fractional equations. This system is discretized by fractional derivatives of Riesz spline wavelets and the collocation method. Then the original problem is transformed into a system

A note on the local behavior of the Taylor method for stiff ODEs Appl. Math. Comput. (IF 3.5) Pub Date : 2025-02-13
Philip P. Forrier, Joan Gimeno, Àngel JorbaIn this note we study the behavior of the coefficients of the Taylor method when computing the numerical solution of stiff Ordinary Differential Equations. First, we derive an asymptotic formula for the growth of the stability region w.r.t. the order of the Taylor method. Then, we analyze the behavior of the Taylor coefficients of the solution when the equation is stiff. Using jet transport, we show

Bipartite leader-following consensus of linear multi-agent systems with unknown disturbances under directed graphs by double dynamic event-triggered mechanism Appl. Math. Comput. (IF 3.5) Pub Date : 2025-02-11
Yuliang Cai, Youtong Wang, Hanguang Su, Lianyan Fu, Qiang HeThis paper addresses the bipartite leader-following consensus problem for general linear multi-agent systems (MASs) with unknown disturbances under directed communication topology. A novel control strategy is proposed to effectively mitigate disturbances and reduce unnecessary triggering actions, thereby conserving resources. The strategy consists of double dynamic event-triggered mechanisms (DDETM)
