Fundamental solution of the time-fractional telegraphDirac operator.Math Meth Appl Sci. 2017;40:7033–7050.https://doi.org/10.1002/mma.4511http://hdl.handle.net/10400.8/7509n this work, we obtain the fundamental solution (FS) of the multidimensionaltime-fractional telegraph Dirac operator where the 2 time-fractional derivatives oforders𝛼∈]0,1]and𝛽∈]1,2]are in the Caputo sense. Explicit integral and seriesrepresentation of the FS are obtained for any dimension. We present and discusssome plots of the FS for some particular values of the dimension and of the frac-tional parameters𝛼and𝛽. Finally, using the FS, we study some Poisson and CauchyproblemsengTime-fractional telegraph and telegraph Dirac operatorsFundamental solutionCaputo fractional derivativeMultivariate Mittag-Leffler functionH-function of two variablesjournal article10.1002/mma.45111099-1476
