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.

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 ...

Oscillatory convection in a dilute3He-superfluid4He solution

Journal of Low Temperature Physics, 1985
Convective instabilities in a rectangular, unity-aspect-ratio Rayleigh-Benard cell with a solution of 1.46%3He in superfluid4He have been studied in the temperature range 0.70–1.05 K, with a corresponding Prandtl number range of 0 ...

Oscillatory solutions of the Falkner-Skan equation

Proceedings of the Royal Society of London. A. Mathematical and Physical Sciences, 1985
The Falkner-Skan equation for similarity solutions of the Prandtl boundary-layer equations for incompressible flow is analysed for both positive and negative values of the parameterβ. Forβ< — 1 branches of solutions with any number of intervals of overshoot are found analytically, and confirm recent numerical results.

Oscillatory solutions of the rate equations

Physics Letters A, 1968
Abstract It is shown that the rate equations for a system relaxing to black body radiation have no oscillatory solutions. A more convenient form of the equations for numerical calculation is given.

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 Solutions of Boundary Value Problems

2016
We consider boundary value problems of the form $$\displaystyle\begin{array}{rcl} & x'' = f(t,x,x'), & {}\\ & x(a) = A,\quad x(b) = B,& {}\\ \end{array}$$ assuming that f is continuous together with f x and fx′. We study also equations in a quasi-linear form $$\displaystyle{x'' + p(t)x' + q(t)x = F(t,x,x').}$$ Introducing types of ...
