We study the global existence and time decay of solutions to nonlinear dispersive wave equations ∂2 t u + 1/ρ2(-Δ)ρ u = F (∂tu) in two space dimensions, where F (∂tu) = λ∂tup-1∂tu or λ∂tup-, λ∈ C; with p > 2 for 0 < ρ < 1; p > 3 for ρ = 1; and p > 1 + ρ for 1 < ρ < 2: If ρ = 1; then the equation converts into the well-known nonlinear wave equation.
