In this article, barycentric interpolation collocation method (BICM) is presented to solve the fractional linear Fredholm-Volterra integro-differential equation (FVIDE). Firstly, the fractional order term of equation is transformed into the Riemann integral with Caputo definition, and this integral term is approximated by the Gauss quadrature formula. Secondly, the barycentric interpolation basis function is used to approximate the unknown function, and the matrix equation of BICM is obtained. Finally, several numerical examples are given to solve one-dimensional differential equation.
本文提出了求解分数阶线性Fredholm-Volterra积分微分方程的质心插值配置法(BICM)。首先,将方程的分数阶项转化为具有Caputo定义的Riemann积分,并用高斯正交公式对该积分项进行近似。其次,利用质心插值基函数逼近未知函数,得到BICM的矩阵方程;最后给出了求解一维微分方程的数值算例。

Changmu Chu, Ying Tang
In the present paper, in view of the variational approach, we discuss the Neumann problems with p x -Laplacian-like operator and nonstandard growth condition, originated from a capillary phenomena. By using the least action principle and fountain theorem, we prove the existence and multiplicity of solutions to the class of Neumann problems under suitable assumptions.
