In this paper, by introducing a relativistic Schrödinger tempered fractional p-Laplacian operator (–Δ)p,λs,m, based on the (–Δ + m2)s and Laplacian (Δ λ)β/2, we consider model involving logarithmic nonlinearity. We first establish maximum principle boundary estimate, which play very crucial role in later process. Then obtain radial symmetry monotonicity results using direct method of moving pla...
