Oscillation criteria for first-order forced nonlinear dynamic equations

Some new criteria for the oscillation of first-order forced nonlinear difference equations of the form Δx(n) + q1(n)xμ(n+ 1) = q2(n)xλ(n+ 1) + e(n), where λ,μ are the ratios of positive odd integers 0 < μ < 1 and λ> 1, are established.
