© 2022Nonlinear Boiti-Leon-Manna-Pempinelli equation (BLMPE) exhibit significant spectral energy transfer for finite amplitude waves in shallow areas above the flat seafloor. In this study, we given solutions to (2+1), (3+1) and (4+1)-dimensional time-fractional BLMP equations representing the wave propagation through incompressible fluids. We found the exact solutions of the high-dimensional time-fractional BLMP equations. Fractional derivative solutions of these equations have not been found in the literature until now. With this study, we have obtained the new exact solutions of both (2+1) dimensional time fractional derivative, (3+1) dimensional time fractional derivative and (4+1) dimensional time fractional derivative BLMP equations.
