Pulsating fronts for nonlocal dispersion and KPP nonlinearity
In this paper we are interested in propagation phenomena for nonlocal reaction-diffusion equations of the type: ∂u ∂t = J ∗ u− u+ f(x, u) t ∈ R, x ∈ R , where J is a probability density and f is a KPP nonlinearity periodic in the xvariables. Under suitable assumptions we establish the existence of pulsating fronts describing the invasion of the 0 state by an heterogeneous state. We also give a ...
متن کاملPlanar Traveling Waves for Nonlocal Dispersion Equation with Monostable Nonlinearity
In this paper, we study a class of nonlocal dispersion equation with monostable nonlinearity in n-dimensional space ut − J ∗ u+ u+ d(u(t, x)) = ∫ Rn fβ(y)b(u(t− τ, x− y))dy, u(s, x) = u0(s, x), s ∈ [−τ, 0], x ∈ Rn, where the nonlinear functions d(u) and b(u) possess the monostable characters like Fisher-KPP type, fβ(x) is the heat kernel, and the kernel J(x) satisfies Ĵ(ξ) = 1 − K|ξ|α + o(|ξ|...
متن کاملMultidimensional Transition Fronts for Fisher-kpp Reactions
We study entire solutions to homogeneous reactiondiffusion equations in several dimensions with Fisher-KPP reactions. Any entire solution 0 < u < 1 is known to satisfy lim t→−∞ sup ∣x∣≤c∣t∣ u(t, x) = 0 for each c < 2 √ f ′(0) , and we consider here those satisfying lim t→−∞ sup ∣x∣≤c∣t∣ u(t, x) = 0 for some c > 2 √ f ′(0) . When f is C and concave, our main result provides an almost complete ch...
متن کاملKPP Pulsating Front Speed-up by Flows
We obtain a criterion for pulsating front speed-up by general periodic incompressible flows in two dimensions and in the presence of KPP nonlinearities. We achieve this by showing that the ratio of the minimal front speed and the effective diffusivity of the flow is bounded away from zero and infinity by constants independent of the flow. We also study speed-up of reaction-diffusion fronts by v...
متن کاملRefined long time asymptotics for the Fisher-KPP fronts
We study the one-dimensional Fisher-KPP equation, with an initial condition u0(x) that coincides with the step function except on a compact set. A well-known result of M. Bramson in [3, 4] states that, as t → +∞, the solution converges to a traveling wave located at the position X(t) = 2t − (3/2) log t + x0 + o(1), with the shift x0 that depends on u0. U. Ebert and W. Van Saarloos have formally...
