Convergence analysis of spectral Tau method for fractional Riccati differential equations

‎In this paper‎, ‎a spectral Tau method for solving fractional Riccati‎ ‎differential equations is considered‎. ‎This technique describes‎ ‎converting of a given fractional Riccati differential equation to a‎ ‎system of nonlinear algebraic equations by using some simple‎ ‎matrices‎. ‎We use fractional derivatives in the Caputo form‎. ‎Convergence analysis of the proposed method is given and rate of‎ ‎convergence is established in the weighted $L^2-$norm‎. ‎Numerical‎ ‎results are presented to confirm the high accuracy of the‎ ‎method‎.
