Chaos prediction in nano-resonators based on nonlocal elasticity theory

open access: yesMATEC Web of Conferences, 2018
By decreasing the thickness of micro- and nano- beams, classical continuum theory is not accurate to predict the static and dynamic response due to the absence of length scale parameter.

A nonlocal problem for loaded partial differential equations of fourth order

open access: yesҚарағанды университетінің хабаршысы. Математика сериясы, 2020
A nonlocal problem for the fourth order system of loaded partial differential equations is considered. The questions of a existence unique solution of the considered problem and ways of its construction are investigated.

Boundary Controllability of Differential Equations with Nonlocal Condition

open access: yesJournal of Mathematical Analysis and Applications, 1999
Global exact boundary controllability in a given time-interval of a semilinear abstract dynamical system is considered. It is generally assumed that the dynamical system is defined in an infinite-dimensional Banach space, that it contains both a linear and a nonlinear part, and that, moreover, it satisfies the so-called nonlocal conditions.

Representations of sl(2,?) in category O and master symmetries [PDF]

open access: yes, 2015
We show that the indecomposable sl(2,?)-modules in the Bernstein-Gelfand-Gelfand category O naturally arise for homogeneous integrable nonlinear evolution systems. We then develop a new approach called the O scheme to construct master symmetries for such

Graph-to-local limit for the nonlocal interaction equation [PDF]

open access: yes, 2023
We study a class of nonlocal partial differential equations presenting a tensor-mobility, in space, obtained asymptotically from nonlocal dynamics on localising infinite graphs.

Nonlocal Symmetries for Time-Dependent Order Differential Equations [PDF]

open access: yesSymmetry, 2018
A new type of ordinary differential equation is introduced and discussed, namely, the time-dependent order ordinary differential equations. These equations can be solved via fractional calculus and are mapped into Volterra integral equations of second kind with singular integrable kernel. The solutions of the time-dependent order differential equations

Existence of Solutions of Nonlinear Differential Equations with Nonlocal Conditions

open access: yesJournal of Mathematical Analysis and Applications, 2000
The authors consider the initial value problem for an abstract nonlinear ordinary differential equation of first order in some Banach space. The initial condition, which is a nonlocal condition, is of the type \(y(0)+ g(y)=y_0\), where \(g\) is some continuous function.
