On the oscillation of higher order dynamic equations

We present some new criteria for the oscillation of even order dynamic equation(a(t)(xΔn-1(t))α)Δ+q(t)(x(t))α=0,a(t)(xΔn-1(t))αΔ+q(t)(x(t))α=0,on time scale T, where α is the ratio of positive odd integers a and q is a real valued positive rd-continuous functions defined on T.
