Thermal Timoshenko beam system with suspenders and Kelvin–Voigt damping

open access: yesFrontiers in Applied Mathematics and Statistics, 2023
In the present study, we consider a thermal-Timoshenko-beam system with suspenders and Kelvin–Voigt damping type, where the heat is given by Cattaneo's law. Using the existing semi-group theory and energy method, we establish the existence and uniqueness

Positive solutions for (p, q)-equations with convection and a sign-changing reaction

open access: yesAdvances in Nonlinear Analysis, 2021
We consider a nonlinear Dirichlet problem driven by the (p, q)-Laplacian and with a reaction which is dependent on the gradient. We look for positive solutions and we do not assume that the reaction is nonnegative.

The concentration-compactness principles for Ws,p(·,·)(ℝN) and application

open access: yesAdvances in Nonlinear Analysis, 2020
We obtain a critical imbedding and then, concentration-compactness principles for fractional Sobolev spaces with variable exponents. As an application of these results, we obtain the existence of many solutions for a class of critical nonlocal problems ...

Effective equation for a system of mechanical oscillators in an acoustic field [PDF]

open access: yes, 2014
We consider a one dimensional evolution problem modeling the dynamics of an acoustic field coupled with a set of mechanical oscillators. We analyze solutions of the system of ordinary and partial differential equations with time-dependent boundary ...

Existence of ground state solutions for critical quasilinear Schrödinger equations with steep potential well

open access: yesAdvanced Nonlinear Studies, 2022
We study the existence of solutions for the quasilinear Schrödinger equation with the critical exponent and steep potential well. By using a change of variables, the quasilinear equations are reduced to a semilinear one, whose associated functionals ...

Positive Solutions for Resonant (p, q)-equations with convection

open access: yesAdvances in Nonlinear Analysis, 2020
We consider a nonlinear parametric Dirichlet problem driven by the (p, q)-Laplacian (double phase problem) with a reaction exhibiting the competing effects of three different terms. A parametric one consisting of the sum of a singular term and of a drift
