Multiplicity and concentration of solutions for Kirchhoff equations with exponential growth

open access: yesBulletin of Mathematical Sciences
In this paper, we deal with fractional [Formula: see text]-Laplace Kirchhoff equations with exponential growth of the form 𝜀ps(a + b[u] s,pp)(−Δ) psu + Z(x)|u|p−2u = h(u)in ℝN, where [Formula: see text] is a positive parameter, [Formula: see text ...

Seismic Imaging of the Westward Transition From Yakutat to Pacific Subduction in Southern Alaska

open access: yesGeochemistry, Geophysics, Geosystems, 2023
Alaska is located at the northernmost point of the interface between the Pacific plate and the North American continent. The subduction of the Pacific plate generates arc volcanoes along the Aleutian trench, which stops to the east at the Denali Volcanic

Existence and Uniqueness of Solutions to Non-Local Problems of Brézis–Oswald Type and Its Application

open access: yesFractal and Fractional
The aim of this paper is to establish the existence and uniqueness of solutions to non-local problems involving a discontinuous Kirchhoff-type function via a global minimum principle of Ricceri.

Positivity for fourth-order semilinear problems related to the Kirchhoff–Love functional [PDF]

open access: yesAnalysis & PDE, 2017
We study the ground states of the following generalization of the Kirchhoff-Love functional, $$J_ (u)=\int_ \dfrac{( u)^2}{2} - (1- )\int_ det(\nabla^2u)-\int_ F(x,u),$$ where $ $ is a bounded convex domain in $\mathbb{R}^2$ with $C^{1,1}$ boundary and the nonlinearities involved are of sublinear type or superlinear with power growth.

Non-stationary influence function for an unbounded anisotropic Kirchhoff-Love shell

open access: yesJournal of Applied Engineering Science, 2020
The purpose of this article is to investigate the process of the influence of a nonstationary load on an arbitrary region of an elastic anisotropic cylindrical shell. The approach to the study of the propagation of forced transient oscillations in the shell is based on the method of the influence function, which represents normal displacements in ...

Optimal Decay Rate Estimates of a Nonlinear Viscoelastic Kirchhoff Plate

open access: yesComplexity, 2020
This paper is concerned with a nonlinear viscoelastic Kirchhoff plate uttt−σΔuttt+Δ2ut−∫0tgt−sΔ2usds=divF∇ut. By assuming the minimal conditions on the relaxation function g: g′t≤ξtGgt, where G is a convex function, we establish optimal explicit and ...

Some remarks on the comparison principle in Kirchhoff equations [PDF]

open access: yes, 2018
In this paper we study the validity of the comparison principle and the sub-supersolution method for Kirchhoff type equations. We show that these principles do not work when the Kirchhoff function is increasing, contradicting some previous results.

Visibility of quantum graph spectrum from the vertices

open access: yes, 2018
We investigate the relation between the eigenvalues of the Laplacian with Kirchhoff vertex conditions on a finite metric graph and a corresponding Titchmarsh-Weyl function (a parameter-dependent Neumann-to-Dirichlet map).

On boundary layer in the Mindlin plate model: Levy plates [PDF]

open access: yes, 2008
This work is related to the bending problem of thick rectangular Levy plates. Series solution for the Mindlin (thick) plate model is obtained and represented as a sum of the Kirchhoff (thin) plate model solution, the ``shear terms'' and the ``boundary ...
