解一类高阶变系数时滞微分系统的新型算法

n this paper, we developed a new method for solving high-order linear delay Fredholm-Volterra integro-differential equations with variable coefficients under the mixed conditions using Chebyshev and Taylor polynomials. The solution is obtained in terms of Chebyshev polynomials on the interval [-1, 1]. In addition, examples are presented to illustrate the pertinent features of the method and the results are discussed.
