Stability of multiple-pulse solutions [PDF]

Transactions of the American Mathematical Society, 1998
In this article, stability of multiple-pulse solutions in semilinear parabolic equations on the real line is studied. A system of equations is derived which determines stability of N N -pulses bifurcating from a stable primary pulse. The system depends only on the particular bifurcation leading to the existence of the N N

Multiple solutions for a class of BVPs of fractional discontinuous differential equations with impulses

AIMS Mathematics, 2023
In this paper, we mainly study the following boundary value problems of fractional discontinuous differential equations with impulses: $ \hskip 3mm \left\{ \begin{array}{lll} _{t}^{C} \mathcal {D}^{\mathfrak{R}}_{0^{+}}\Lambda(t) = \mathcal {E}(t ...

Multiple solutions to Gierer-Meinhardt systems of elliptic equations [PDF]

arXiv, 2022
We establish the existence of multiple solutions for Gierer-Meinhardt system involving Neumann boundary conditions. The approach combines the methods of sub-supersolution and Leray-Schauder topological degree.

Multiplicity of solutions for the bounce problem

Journal of Differential Equations, 1984
AbstractThe bounce trajectories in a convex set which assume assigned positions in two fixed time instants are sought. Sufficient conditions in order to obtain the existence of infinitely many bounce trajectories are found.

Multiple Solutions of Double-Diffusive Convection in Porous Media due to Opposing Heat and Mass Fluxes on Vertical Walls

Journal of Thermal Science and Technology, 2013
The double-diffusive convection in a porous medium due to the opposing heat and mass fluxes on the vertical walls is solved analytically. In the former analysis, we investigated only when ω < π, the parameter arising from a combination among ...

Infinitely many nodal solutions for a class of quasilinear elliptic equations

Electronic Journal of Qualitative Theory of Differential Equations, 2021
In this paper, we study the existence of infinitely many nodal solutions for the following quasilinear elliptic equation \begin{equation*} \begin{cases} -\nabla\cdot\left[\phi'(|\nabla u|^2)\nabla u\right]+|u|^{\alpha-2}u=f(u) , \quad x\in \mathbb{R}^N,\\

Population and species neighbor identity impact trait–trait relationships and plant performance

Population Ecology, EarlyView.
We evaluated how populations and species identity influence plant performance and trait outcomes in mixtures, and assessed trait variation among populations of two forb species native to the western United States (Dieteria canescens and Heterotheca villosa) following three interaction treatments (single‐population monoculture, two‐population mixture ...
