The concerted emergence of well-known spatial and temporal ecological patterns in an evolutionary food web model in space

Our computer simulations show that the model gives rise simultaneously to several biodiversity patterns in space and time, from species abundance distributions to the waxing and waning of geographic ranges. Expand abstract.

The linearly damped nonlinear Schr\"odinger equation with localized driving: spatiotemporal decay estimates and the emergence of extreme wave events

Their derivation is made via a scheme, which incorporates suitable weighted Sobolev spaces and a time-weighted energy method. Expand abstract.

C4 Space-Time.. A Window to New Physics?

By embedding our usual 4-d real space-time in the symplectic 8-d real space-time (symplectic R8 is algebraically isomorphic to C4), we derive the usual geodesic equation of a charged particle in gravitational eld, plus new information which is interpreted. Expand abstract.

A space-time hybridizable discontinuous Galerkin method for linear free-surface waves

In order to show well-posedness, our space-time HDG formulation makes use of weighted inner products. Expand abstract.

Global Existence of Strong Solutions to the Kinetic Cucker--Smale Model Coupled with the Stokes Equations

By introducing a weighted Sobolev space and using space-time estimates for the linear non-stationary Stokes equations, we present a complete analysis on existence of global-in-time strong solutions to the coupled model, without any smallness requirements on initial data. Expand abstract.

Waves of space-time from a collapsing compact object

We study the partial time dependent collapse of a spherically symmetric compact object with initial mass $M_1+M_2$ and final mass $M_2$ and the waves of space-time emitted during the collapse via back-reaction effects. Expand abstract.

On the initial value problem for the electromagnetic wave equation in Friedmann-Robertson-Walker space-times

We solve the source free electromagnetic wave equation in Friedmann-Robertson-Walker space-times for curvature $K=0$ and $K=-1$. Expand abstract.

Existence of global weak solutions to the Navier-Stokes equations in weighted spaces

We obtain a global existence result for the three-dimensional Navier-Stokes equations with a large class of data allowing growth at spatial infinity. Expand abstract.

Monitoring the prolonged TNF stimulation in space and time with topological-functional networks
