A set of seismic observations which all sample the same structure in the same way should have zero variance. This is naturally the case if all sources are in the same place, and the data are recorded ...
On the Muskat problem: global in time results in 2D and 3D
Porous media incompressible ows uid interface global existence.

This paper considers the three dimensional Muskat problem in the stable regime.We obtain a conservation law which provides an L2 maximum principle for the uid interface. We also show global in time ex...

Abstract: We investigate a fractional diffusion/anti-diffusion equation proposed by Andrew C. Fowler to describe the dynamics of sand dunes sheared by a fluid flow. In this paper, we prove the global-...

In this paper, we simplify and extend the results of [GZ] to in-clude the case in which = R3. Let [L2(R3)]3 be the Hilbert space of square integrable functions on R3 and let H[R3]3 =: H be the comple...
Fundamental Solution Global in Time for a Class of Schrödinger Equations with Time-Dependent Potentials

Fundamental solution for a Schrödinger equation with a time-dependent potential of
long-range type is constructed. The solution is given as a Fourier integral operator with
a symbol uniformly b...

We consider the Cauchy problem ${\varepsilon}{u_{\ep}}''+\delta{u_{\ep}}'+A{u_{\varepsilon}}=0,$ ${u_{\varepsilon}}(0)=u_0, $ ${u_{\varepsilon}}'(0)=u_{1},$ where ${\varepsilon}>0$, $\delta>0$, $H$ is...
