Abstract: This paper investigates the (2+1)-dimensional Bogoyavlensky–Konopelchenko equation with variable coefficients via the generalized unified method. Mixed type of N-soliton solutions are obtained when N=1 $ N=1 $ and N=2 $ N=2 $ in a rational form. The propagation and the dynamical behavior of these solutions is analyzed for different choices of the arbitrary variable coefficients. When N=1 $ N=1 $ , it is verified that the velocity of the soliton cannot be influenced by the variable coefficients. Furthermore, the shape and the amplitude of the soliton cannot be affected. For N=2 $ N=2 $ , the collision between the solitons, either two kink periodic soliton solutions or two kink and anti-kink soliton solutions, are elastic whether the coefficients of the equation are constant or variable.
