Continuous and discrete periodic asymptotic behavior of solutions to a competitive chemotaxis PDEs system

open access: yesCommunications in Nonlinear Science and Numerical Simulation, 2021
In this paper we study the continuous and full discrete versions of a parabolic-parabolic-elliptic system with periodic terms that serves as a model for some chemotaxis phenomena. This model appears naturally in the interaction of two biological species and a chemical.

Multiple patterns formation for an aggregation/diffusion predator-prey system

open access: yesNetworks and Heterogeneous Media, 2021
We investigate existence of stationary solutions to an aggregation/diffusion system of PDEs, modelling a two species predator-prey interaction. In the model this interaction is described by non-local potentials that are mutually proportional by a ...

Sharp interface limit in a phase field model of cell motility

open access: yesNetworks and Heterogeneous Media, 2017
We consider a phase field model of cell motility introduced in [40] which consists of two coupled parabolic PDEs. We study the asymptotic behavior of solutions in the limit of a small parameter related to the width of the interface (sharp interface limit)

On explosive solutions for a class of quasi-linear elliptic equations [PDF]

open access: yes, 2012
We study existence, uniqueness, multiplicity and symmetry of large solutions for a class of quasi-linear elliptic equations. Furthermore, we characterize the boundary blow-up rate of solutions, including the case where the contribution of boundary ...

Doubly Spinning Black Rings [PDF]

open access: yes, 2006
We study a method to solve stationary axisymmetric vacuum Einstein equations numerically. As an illustration, the five-dimensional doubly spinning black rings that have two independent angular momenta are formulated in a way suitable for fully nonlinear ...

Nonlinear PDEs for gap probabilities in random matrices and KP theory [PDF]

open access: yes, 2012
Airy and Pearcey-like kernels and generalizations arising in random matrix theory are expressed as double integrals of ratios of exponentials, possibly multiplied with a rational function. In this work it is shown that such kernels are intimately related

Asymptotically Hyperbolic Non Constant Mean Curvature Solutions of the Einstein Constraint Equations [PDF]

open access: yes, 1996
We describe how the iterative technique used by Isenberg and Moncrief to verify the existence of large sets of non constant mean curvature solutions of the Einstein constraints on closed manifolds can be adapted to verify the existence of large sets of ...

Residual equilibrium schemes for time dependent partial differential equations [PDF]

open access: yes, 2016
Many applications involve partial differential equations which admits nontrivial steady state solutions. The design of schemes which are able to describe correctly these equilibrium states may be challenging for numerical methods, in particular for high ...

A class of second-order geometric quasilinear hyperbolic PDEs and their application in imaging science [PDF]

open access: yes, 2019
In this paper, we study damped second-order dynamics, which are quasilinear hyperbolic partial differential equations (PDEs). This is inspired by the recent development of second-order damping systems for accelerating energy decay of gradient flows.

The Cauchy problem for the Pavlov equation [PDF]

open access: yes, 2014
Commutation of multidimensional vector fields leads to integrable nonlinear dispersionless PDEs arising in various problems of mathematical physics and intensively studied in the recent literature.
