چکیده

<p style='text-indent:20px;'>A depletion-type reaction-diffusion Gierer-Meinhardt model with Langmuir-Hinshelwood reaction scheme and the homogeneous Neumann boundary conditions is introduced investigated in this paper. Firstly, boundedness of positive solution parabolic system given, constant steady state solutions are exhibited by Shengjin formulas. Through rigorous theoretical analysis, stability corresponding explored. Next, a priori estimates, properties nonconstant states, non-existence existence for elliptic some estimates Leray-Schauder degree theory, respectively. Then, established Hopf bifurcation presented, It showed that temporal spatial structures will appear model. Theoretical results confirmed complemented numerical simulations.</p>

Dynamics and stability of spike-type solutions to a one dimensional Gierer-Meinhardt model with sub-diffusion

The dynamics and stability of spike-type patterns to a sub-diffusive Gierer-Meinhardt reaction – diffusion system is studied in a one dimensional spatial domain. A differential algebraic system (DAE) is derived to characterise the dynamics of an n-spike quasi-equilibrium pattern in the presence of subdiffusion. With sub-diffusive effects it is shown that quasi-equilibrium spike patterns exist f...

On the Gierer-meinhardt System with Precursors

We consider the following Gierer-Meinhardt system with a precursor μ(x) for the activator A in R:    At = 2A ′′ − μ(x)A + A2 H in (−1, 1), τHt = DH ′′ −H + A in (−1, 1), A′(−1) = A′(1) = H ′(−1) = H ′(1) = 0. Such an equation exhibits a typical Turing bifurcation of the second kind, i.e., homogeneous uniform steady states do not exist in the system. We establish the existence and stabili...

On the Gierer-meinhardt System with Saturation

We consider the following shadow system of the GiererMeinhardt system with saturation: ⎧⎪⎨ ⎪⎩ At = 2∆A−A+ A2 ξ(1+kA2) in Ω× (0,∞), τξt = −ξ + 1 |Ω| ∫ Ω A dx in (0,+∞), ∂A ∂ν = 0 on ∂Ω× (0,∞), where > 0 is a small parameter, τ ≥ 0, k > 0 and Ω ⊂ R is smooth bounded domain. The case k = 0 has been studied by many authors in recent years. Here we give some sufficient conditions on k for the existe...

Delayed Reaction Kinetics and the Stability of Spikes in the Gierer-Meinhardt Model

A linear stability analysis of localized spike solutions to the singularly perturbed two-component Gierer-Meinhardt (GM) reaction-diffusion (RD) system with a fixed time-delay T in the nonlinear reaction-kinetics is performed. Our analysis of this model is motivated by the computational study of Seirin Lee et al. (2010) [13] on the effect of gene expression time delays on spatial patterning for...
