Existence of mild solutions for fractional nonautonomous evolution equations of Sobolev type with delay [PDF]

open access: yesJournal of Inequalities and Applications, 2017
In this paper, we deal with a class of nonlinear fractional nonautonomous evolution equations with delay by using Hilfer fractional derivative, which generalizes the famous Riemann-Liouville fractional derivative. The definition of mild solutions for the

Root Operators and “Evolution” Equations [PDF]

open access: yesMathematics, 2015
Root-operator factorization à la Dirac provides an effective tool to deal with equations, which are not of evolution type, or are ruled by fractional differential operators, thus eventually yielding evolution-like equations although for a multicomponent ...

Evolution of the Wilson–Cowan equations [PDF]

open access: yesBiological Cybernetics, 2021
The Wilson-Cowan equations were developed to provide a simplified yet powerful description of neural network dynamics. As such, they embraced nonlinear dynamics, but in an interpretable form. Most importantly, it was the first mathematical formulation to emphasize the significance of interactions between excitatory and inhibitory neural populations ...

Some approximation results for mild solutions of stochastic fractional order evolution equations driven by Gaussian noise. [PDF]

open access: yesStoch Partial Differ Equ, 2023
We investigate the quality of space approximation of a class of stochastic integral equations of convolution type with Gaussian noise. Such equations arise, for example, when considering mild solutions of stochastic fractional order partial differential ...

Stochastic reaction–diffusion equations on networks [PDF]

open access: yes, 2021
We consider stochastic reaction–diffusion equations on a finite network represented by a finite graph. On each edge in the graph, a multiplicative cylindrical Gaussian noise-driven reaction–diffusion equation is given supplemented by a dynamic Kirchhoff ...

Evolution equations of translational-rotational motion of a non-stationary triaxial body in a central gravitational field [PDF]

open access: yesTheoretical and Applied Mechanics, 2020
The translational-rotational motion of a triaxial body with constant dynamic shape and variable size and mass in a non-stationary Newtonian central gravitational field is investigated. Differential equations of motion of the triaxial body in the relative
