Existence of a solution for a m-biharmonic Kirchhoff type equation

, 2023
In this thesis, we proved the existence of a ground-state solution for the following $m$-biharmonic Kirchhoff-type equation. \begin{equation} (P_\lambda)\left\{\begin{array}{l} \displaystyle \Delta_{m}^{2} u(x)-\left[ a \left( \int_{\Omega}\mid ...

Recent Advances in the Study of a Fourth-Order Compact Scheme for the One-Dimensional Biharmonic Equation

, 2012
International audienceIt is well-known that non-periodic boundary conditions reduce considerably the overall accuracy of an approximating scheme. In previous papers the present authors have studied a fourth-order compact scheme for the one-dimensional ...

On a class of a boundary value problems involving the p(x)-Biharmonic operator

, 2019
Our aim is to establish the existence of weak solution for a class of Robin problems involving fourth order operator. The nonlinearity is superlinear but does not satisfy the usual Ambrosetti-Rabinowitz condition.The proof is made with and without ...

Ground state solutions and least energy sign-changing solutions for a class of fourth order Kirchhoff-type equations in RN

, 2017
In this article we study the problem Δ2u−(1+λ∫RN|∇u|2dx)Δu+V(x)u=|u|p−2uin  RN, where Δ2≔Δ(Δ) is the biharmonic operator, λ>0 is a parameter, p∈(2,2∗), and V(x)∈C(RN,R). Under appropriate assumptions on V(x), the existence of ground state solutions and a

Transmogrification: casual manipulation of visualizations

, 2013
A transmogrifier is a novel interface that enables quick, on-the-fly graphic transformations. A region of a graphic can be specified by a shape and transformed into a destination shape with real-time, visual feedback.

Biharmonic elliptic problems involving the 2nd Hessian operator

, 2014
In this paper we will study the equation $$\Delta^2 u=S_2(D^2u),\quad \Omega\subset\mathbb{R}^N,$$ with $N=3,$ where $ S_2(D^2u)(x)=\sum_{1\leq i0$, and ...
