Forced oscillation criteria for quasilinear elliptic inequalities with p(x)-Laplacian are derived by using the Riccati inequality.The approach used is to reduce forced oscillation problems for quasilinear elliptic inequalities with p(x)-Laplacian to one-dimensional oscillation problems for Riccati inequalities with variable exponents.More general quasilinear elliptic inequalities with mixed nonlinearities are also investigated.
