Comparison theorems for fourth order differential equations
International Journal of Mathematics and Mathematical Sciences, 1986 This paper establishes an apparently overlooked relationship between the pair of fourth order linear equations yiv−p(x)y=0 and yiv+p(x)y=0, where p is a positive, continuous function defined on [0,∞).

Stochastic homogenization of interfaces moving with changing sign velocity [PDF]
, 2014 We are interested in the averaged behavior of interfaces moving in stationary ergodic environments, with oscillatory normal velocity which changes sign.

A modified particle method for semilinear hyperbolic systems with oscillatory solutions [PDF]
, 2004 We introduce a modified particle method for semi-linear hyperbolic systems with highly oscillatory solutions. The main feature of this modified particle method is that we do not require different families of characteristics to meet at one point.

DEEP NEURAL NETWORK SOLUTIONS FOR OSCILLATORY FREDHOLM INTEGRAL EQUATIONS
Journal of Integral Equations and ApplicationsWe studied the use of deep neural networks (DNNs) in the numerical solution of the oscillatory Fredholm integral equation of the second kind. It is known that the solution of the equation exhibits certain oscillatory behaviors due to the oscillation of the kernel.

Nonoscillation theorems for functional differential equations of arbitrary order
International Journal of Mathematics and Mathematical Sciences, 1984 The authors give sufficient conditions for all oscillatory solutions of a sublinear forced higher order nonlinear functional differential equation to converge to zero. They then prove a nonoscillation theorem for such equations.

Bounded damped oscillatory solutions of Fisher equation
Acta Physica Sinica, 2012 To research the bounded damped oscillatory solutions of nonlinear evolution equation, we choose the Fisher equation as an example. The solutions with negative amplitudes of Fisher equation may become meaningful in the context of nonscalar models describing excitable media (e.g. the Belousov-Zhabotinsky (BZ) reaction).
