We establish oscillation criteria for the second-order elliptic differential equation $$ ablacdot(A(x) abla y)+B^T(x) abla y+q(x)f(y)=e(x), quad xinOmega, $$ where $Omega $ is an exterior domain in $mathbb{R}^N$. These criteria are different from mos

New oscillation criteria are established for the nonlinear matrix differential equations with a forced term $$ [ r(t)Y'(t)] '+p(t)Y'(t)+Q(t)G( Y'(t)) F( Y(t)) =e(t)I_n. $$ Our results extend and improve the recent results of Li and Agarwal for scalar

In this paper, some new oscillation criteria are obtained for second order elliptic differential equations with damping of the form ∇ ⋅ ( A ( x ) ∇ y ) + B T ( x ) ∇ y + q ( x ) f ( y ) = 0 , x ∈ Ω , where Ω is an exterior domain in R N .

This paper is concerned with oscillation of second-order nonlinear neutral dynamic equations on time scales with a variable delay. By using the generalized Riccati technique and integral averaging technique, new oscillation criteria are obtained for
