  We obtain new exact classes of solutions for the nonlinear fractional
Fokker-Planck-like equation partial_t rho = partial_x{D(x) partial^{mu -1}_x
rho^{nu} - F(x) rho} by considering a diffusion coefficient D = D|x|^{-theta}
(theta in R and D>0) and a drift force F = -k_1 x + k-bar_{gamma}
x|x|^{gamma-1} (k_1, k-bar_{gamma}, gamma in R). Connection with nonextensive
statistical mechanics based on Tsallis entropy is also discussed.
