Sharp oscillation criteria for fourth order sub-half-linear and super-half-linear differential equations

This paper is concerned with the oscillatory behavior of the fourth-order nonlinear differential equation $$ \bigl(p(t)|x^{\prime\prime}|^{\alpha-1}\,x^{\prime\prime}\bigr)^{\prime\prime} +q(t)|x|^{\beta-1}x=0\,,\tag{E} $$ where $\alpha>0$, $\beta>0$ are constants and $p,q:[a,\infty)\to(0,\inf...
