RT Journal Article T1 Analytical solutions for fractional partial delay differential-algebraic equations with Dirichlet boundary conditions defined on a finite domain A1 Ding, Xiao-Li A1 Nieto Roig, Juan José A1 Wang, Xiaolong K1 Fractional partial differential-algebraic equations with delays K1 Dirichlet boundary condition K1 Fractional Laplacian operator K1 Spectral representation K1 Analytical solution AB In this paper, we investigate the solution of multi-term time-space fractional partial delay differential-algebraic equations (MTS-FPDDAEs) with Dirichlet boundary conditions defined on a finite domain. We use Laplace transform method to give the solutions of multi-term time fractional delay differential-algebraic equations (MTS-FDDAEs). Then, the technique of spectral representation of the fractional Laplacian operator is used to convert the MTS-FPDDAEs into the MTS-FDDAEs. By applying our obtained solutions to the resulting MTS-FDDAEs, the desired analytical solutions of the MTS-FPDDAEs are obtained. Finally, we give the solutions of some special cases PB Springer SN 1311-0454 YR 2022 FD 2022 LK http://hdl.handle.net/10347/29202 UL http://hdl.handle.net/10347/29202 LA eng NO Fractional Calculus and Applied Analysis 25, 408–438 (2022). https://doi.org/10.1007/s13540-022-00021-7 NO This work was supported by the Natural Science Foundation of China (NSFC) under grants 11871400.
