Existence and non-existence results for the higher order Hardy–Hénon equations revisited

نویسندگان

چکیده

This paper is devoted to studies of non-negative, non-trivial (classical, punctured, or distributional) solutions the higher order Hardy-H\'enon equations \[ (-\Delta)^m u = |x|^\sigma u^p \] in $\mathbf R^n$ with $p > 1$. We show that condition n - 2m \frac{2m+\sigma}{p-1} >0 necessary for existence distributional solutions. For $n \geq 2m$ and $\sigma -2m$, we prove any solution satisfies an integral equation a weak super polyharmonic property. establish some sufficient conditions punctured classical be solution. As application, if there no non-trivial, 1 < p \frac{n+2m+2\sigma}{n-2m}. At last, 2m$, -2m$ $$p \frac{n+2m+2\sigma}{n-2m},$$ exist positive, radially symmetric, equation.

Existence and uniqueness results for a nonlinear differential equations of arbitrary order

This paper studies a fractional boundary value problem of nonlinear differential equations of arbitrary orders. New existence and uniqueness results are established using Banach contraction principle. Other existence results are obtained using Schaefer and Krasnoselskii fixed point theorems. In order to clarify our results, some illustrative examples are also presented.

Existence and Non Existence of Solitons for a 1d Benney-luke Model of Higher Order

We shall establish the existence and non existence of solitons (travelling waves of finite energy) for a Benney-Luke equation of higher order, which includes models for long water waves with small amplitude. Following a variational approach, solitons are characterized as critical points of the action functional. Existence of solitons follows by the ConcentrationCompactness principle by P.-L. Li...
