报告摘要:In this work, we designed a distributed-order Gauss-Quadrature scheme to approximate solutions for distributed-order mathematical models. Quadrature rules and their applications have been primarily noted with respect to special functions like Legendre, Bernstein, Hermite, and others. In this work, we establish a numerical scheme based on the given weight function in the proposed mathematical models. The designed scheme depends entirely on a single input function known as the distributed-order weight function, alongside the development of an orthogonal generating polynomial (OGP). The proposed problem has been solved numerically with the help of the OGP Gauss Quadrature rule along with an operational matrix based on the designed OGP technique. Theoretical error bounds, stability analysis, and efficiency are rigorously investigated and a comprehensive set of examples are provided to validate the reliability and accuracy of the proposed numerical scheme.
