The stability of solutions to delay differential equations in Banach spaces
Известия высших учебных заведений. Поволжский регион: Физико-математические науки, 2023 Background. The work is devoted to the analysis of stability in the sense Lyapunov of steady-state solutions of nonlinear differential equations in Banach spaces with time-dependent operators and with time-dependent delays.

Nonlinear properties of AlGaAs waveguides in continuous wave operation regime [PDF]
Optics Express, 2014 Aluminum Gallium Arsenide (AlGaAs) is an attractive platform for the development of integrated optical circuits for all-optical signal processing thanks to its large nonlinear coefficients in the 1.55-μm telecommunication spectral region. In this paper we discuss the results of the nonlinear continuous-wave optical characterization of AlGaAs waveguides

On strong convex compactness property of spaces of nonlinear operators [PDF]
Bulletin of the Australian Mathematical Society, 2006 The strong convex compactness property is important for property persistence of operator semigroups under perturbations. It has been investigated in the linear setting. In this paper, we are concerned with the property in the nonlinear setting. We prove that the following spaces of (nonlinear) operators enjoy the strong convex compactness property: the

Some properties of nonlinear Volterra-Stieltjes integral operators
Computers & Mathematics with Applications, 2005 We study some properties of the nonlinear Volterra-Stieltjes integral operator of general form which is defined with help of the Stieltjes integral with the kernel depending on two variables. The results obtained in the paper generalize those obtained earlier for the Volterra-Stieltjes integral operators having less general form.

The nonlocal problem for fractal diffusion equation
Міжнародний науково-технічний журнал "Проблеми керування та інформатики", 2023 Over the past few decades, the theory of pseudodifferential operators (PDO) and equations with such operators (PDE) has been intensively developed. The authors of a new direction in the theory of PDE, which they called parabolic PDE with non-smooth ...
