摘要:New oscillation criteria are established for higher-order Emdn-Fowler dynamic equation$ q(v)x^{\beta } (\delta (v)) + (r(v)(z^{{\Delta ^{{n - 1}} }} (v))^{\alpha } )^{\Delta } = 0 $on time scales,$ z(v): = p(v)x(\tau (v)) + x(v) $Our results extend and supplement those reported in literatures in the sense that we study a more generalized neutral delay equation and do not require$ r^{\Delta } (v) \ge 0 $and the commutativity of the jump and delay operators.
