The solution of the equation is presented in terms of bivariate Mittag-Leffler functions. An asymptotic analysis of the solution of the associated homogeneous equation is performed.engFractional relaxation-oscillation equationpsi-Hilfer derivativeBivariate Mittag-Leffler functionPsi-Hilfer fractional relaxation-oscillation equationconference object
