A mixed formulation with two main variables, based on the Ciarlet-Raviart technique, with 0 C continuity shape functions is employed for the solution of some types of biharmonic equations in 1-D. The continuous and discrete Babuška-Brezzi inf-sup conditions are established. The formulation is numerically tested for both the hand pextensions. The model problems involve the standard biharmonic eq...
using variational arguments, we prove the existence of infinitely many solutions to a class of $p$-biharmonic equation in $mathbb{r}^n$. the existence of nontrivial solution is established under a new set of hypotheses on the potential $v(x)$ and the weight functions $h_1(x), h_2(x)$.
In this paper biharmonic maps between doubly warped product manifolds are studied. We show that the inclusion maps of Riemannian manifolds B and F into the doubly warped product f B ×b F can not be proper biharmonic maps. Also we analyze the conditions for the biharmonicity of projections f B ×b F → B and f B ×b F → F , respectively. Some characterizations for non-harmonic biharmonic maps are g...
We study the positive, regular, radially symmetric solutions to the nonlinear biharmonic equation ∆φ = φ. First, we show that there exists a critical value pc, depending on the space dimension, such that the solutions are linearly unstable if p < pc and linearly stable if p ≥ pc. Then, we focus on the supercritical case p ≥ pc and we show that the graphs of no two solutions intersect one another.
