Abstract

In this work, the existence and uniqueness solution of the fractional nonlinear mixed integro-differential equation (FrNMIoDE) is guaranteed with a general discontinuous kernel based on position and time-space L2Ω×C0,T, T<1. The FrNMIoDE conformed to the Volterra-Hammerstein integral equation (V-HIE) of the second kind, after applying the characteristics of a fractional integral, with a general discontinuous kernel in position for the Hammerstein integral term and a continuous kernel in time to the Volterra integral (VI) term. Then, using a separation technique methodology, we developed HIE, whose physical coefficients were time-variable. By examining the system’s convergence, the product Nystrom technique (PNT) and associated schemes were employed to create a nonlinear algebraic system (NAS).

分数阶非线性混合积分微分方程的一个物理现象

本文在位置和时空L2Ω×C0，T，T<1的基础上，用一般不连续核保证了分数阶非线性混合积分微分方程（FrNMIoDE）的存在唯一解。FrNMIoDE在应用分数积分的特性后，符合第二类Volterra Hammerstein积分方程（V-HIE），Hammerstein整数项在位置上具有一般不连续核，Volterra积分（VI）项在时间上具有连续核。然后，使用分离技术方法，我们开发了HIE，其物理系数是时变的。通过检验系统的收敛性，采用乘积Nystrom技术（PNT）和相关方案创建了一个非线性代数系统（NAS）。
