Oscillatory Solutions of Fractional Integro-Differential Equations

Mathematical Methods in the Applied Sciences, 2020
We give necessary conditions to get oscillatory solutions of a class of fractional order neutral differential equations with continuously distributed delay by means of the fractional derivative with respect to a given function. In particular, oscillatory solutions of the considered fractional equations with Caputo and Hadamard type of fractional ...

Effect of oscillatory shear on polymer solutions

Physical Review E, 2002
We consider the effects of oscillatory shear flow on small concentration fluctuations in polymer solutions, which we model as highly asymmetric entangled polymer blends. A simple model that enables us to predict the scattering patterns in the flow-vorticity plane is presented.

On Oscillatory Solutions of Quasilinear Differential Equations

open access: yesJournal of Mathematical Analysis and Applications, 2006
The authors present necessary and sufficient conditions for the existence of at least one oscillatory solution of a second-order quasilinear differential equation. The results obtained yield also new conditions guaranteeing the coexistence of oscillatory and nonoscillatory solutions.

Oscillatory Hydrogen Solution in ZrV2

physica status solidi (b), 1999
The effect of the solution of small amounts of hydrogen on the structure and structural phase transformation of the intermetallic compound ZrV 2 was studied using X-ray analysis and differential calorimetry. Additional maximum sattelites appeared in X-ray diffractograms after cooling of the hydrogen containing intermetallic ZrV 2 below T = 150 to 160 ...

On Connectedness: A Solution Based on Oscillatory Correlation

Neural Computation, 2000
A long-standing problem in neural computation has been the problem of connectedness, first identified by Minsky and Papert (1969). This problem served as the cornerstone for them to establish analytically that perceptrons are fundamentally limited in computing geometrical (topological) properties.

Oscillatory properties of solutions of the equations

Applicable Analysis, 1996
We study the oscillation and nonoscillat,ion of solutions of the two equations Also, for the (-) equation conditions for the faster-than-exponential growth and decay of solutions are obtained. Properties of the characteristic equations are used.

Unbounded Oscillatory Solutions for a System of Interacting Populations

SIAM Journal on Applied Mathematics, 1985
A class of autonomous systems of three ordinary differential equations is studied, some of whose examples arise from models of interacting populations. This class of systems always has a unique equilibrium, and the Jacobian matrix at that equilibrium has one negative eigenvalue and two complex eigenvalues with positive real part.
