Oscillation Criteria for Second-Order Superlinear Neutral Differential Equations

and Applied Analysis 3 where τ t ≤ t, σ t ≤ t, τ ′ t τ0 > 0, 0 ≤ p t ≤ p0 < ∞, and the authors obtained some oscillation criteria for 1.7 . However, there are few results regarding the oscillatory problem of 1.1 when τ t ≥ t and σ t ≥ t. Our aim in this paper is to establish some oscillation criteria for 1.1 under the case when τ t ≥ t and σ t ≥ t. The paper is organized as follows. In Section ...

SOME RESULTS FOR SOLUTION AND FOCAL POINTS OF NONSELFADJOINT SECOND ORDER SYSTEMS

Consider y" (t) + A (t)y (t) + 0, y is a real n-dimensinal vector and A(t) is a real nxn matrix, continuous on some interval. Some positivity properties of solutions and conjugate points of y"(t) + A(t)y (t) = 0 appeared in literature. We prove similar results for focal points

Initial value problems for second order hybrid fuzzy differential equations

Usage of fuzzy differential equations (FDEs) is a natural way to model dynamical systems under possibilistic uncertainty. We consider second order hybrid fuzzy differentia

Some Oscillation Results for Second Order Neutral Type Difference Equations

This paper is concerned with the oscillatory behavior of second order neutral difference equations. Four oscillation theorems for such equations are established and examples are given to illustrate the results. Mathematics subject classification (2010): 39A11.
