A chebyshev-laguerre-gauss-radau collocation scheme for solving a time fractional sub-diffusion equation on a semi-infinite domain. Proceedings Of The Romanian Academy Series A-Mathematics Physics Technical Science Information Science, 16(4), 490-498.http://hdl.handle.net/20.500.12416/1552We propose a new efficient spectral collocation method for solving a time fractional sub-diffusion equation on a semi-infinite domain. The shifted Chebyshev-Gauss-Radau interpolation method is adapted for time discretization along with the Laguerre-Gauss-Radau collocation scheme that is used for space discretization on a semi-infinite domain. The main advantage of the proposed approach is that a spectral method is implemented for both time and space discretizations, which allows us to present a new efficient algorithm for solving time fractional sub-diffusion equationsenginfo:eu-repo/semantics/closedAccessTime Fractional Sub-Diffusion EquationSemi-Infinite DomainChebyshev-Gauss-Radau Collocation SchemeCaputo Derivativesarticle164490498
