【Abstract】 This paper deals with the differential equations with double-pantograph delay. We prove the existence of collocation solution and study the Pade approximation of the analytic solution and its existence. In our consideration, we find that the relation between the collocation method and the Pade approximation is determined by multi-integration of the collocation polynomial. The determined method of the collocation polynomial is given out. A numerical experiment is presented to verify the main result that the attainable order of the collocation method is 2m+1.更多还原
