چکیده
This paper is concerned with traveling wave solutions in a discrete diffusion epidemic model delayed transmission. Employing the way of contradictory discussions and bilateral Laplace transform, we obtain nonexistence nontrivial positive bounded solutions. Utilizing super-/sub-solutions method fixed point theory, derive existence both super-critical critical speeds. Our results indicate that speed minimal speed.

Stability and Traveling Waves of an Epidemic Model with Relapse and Spatial Diffusion∗
An epidemic model with relapse and spatial diffusion is studied. Such a model is appropriate for tuberculosis, including bovine tuberculosis in cattle and wildlife, and for herpes. By using the linearized method, the local stability of each of feasible steady states to this model is investigated. It is proven that if the basic reproduction number is less than unity, the diseasefree steady state...
متن کاملTraveling avalanche waves in spatially discrete bistable reaction–diffusion systems
Infinitely extended two-dimensional reaction–diffusion lattices composed of bistable cells are considered. A class of particular stable stationary solutions, called pattern solutions, is introduced and examples are given. Pattern solutions persist at high diffusion coefficients whereas all other stable stationary solutions, with the exception of the constant solutions, disappear one after the o...
متن کاملTraveling Waves in the Holling-tanner Model with Weak Diffusion
For wide range of parameters, we study traveling waves in a diffusive version of the Holling-Tanner predator-prey model from population dynamics. Fronts are constructed using geometric singular perturbation theory and the theory of rotated vector fields. We focus on the appearance of the fronts in various singular limits. In addition, periodic traveling waves of relaxation oscillation type are ...
متن کاملStability of non-monotone critical traveling waves for reaction–diffusion equations with time-delay
This paper is concerned with the stability of critical traveling waves for a kind of non-monotone timedelayed reaction–diffusion equations including Nicholson’s blowflies equation which models the population dynamics of a single species with maturation delay. Such delayed reaction–diffusion equations possess monotone or oscillatory traveling waves. The latter occurs when the birth rate function...
متن کاملTraveling waves for anomalous diffusion in polymers
case II diffusion of a penetrant through a polymer matrix is characterized by constant front speed. Hence, a traveling-wave analysis is appropriate for the model equations. For the previously validated model analyzed here, conditions on the molecular and stress diffusion coefficients are obtained which guarantee the existence of a traveling wave. Conditions are derived under which an interior m...
