Fading memory and the problem of approximating nonlinear operators with Volterra series
Continuous nonlinear operator volterra series operator nonlinear dynamic system
2015/8/13
Using the notion of fading memory, very strong versions of two theorems are proved. The first is that any time-invariant (TI) continuous nonlinear operator can be approximated by a Volterra series ope...
Riemann-Hilbert Problems with canonical normalization and families of commuting operators
Riemann-Hilbert Problems commuting operators integrable 3-wave interactions
2012/4/26
We start with a Riemann-Hilbert Problems (RHP) with canonical normalization whose sewing functions depends on several additional variables. Using Zakharov-Shabat theorem we are able to construct a fam...
Homogenization of a class of integro-differential equations with L{é}vy operators
Homogenization of a class integro-differential equations L{é}vy operators
2011/2/22
We study the periodic homogenization of u"−c( x" ) Zz∈RN [u"(x+z)−u"(x)−1|z|<1h∇u"(x).
Ito diffusions, modified capacity and harmonic measure. Applications to Schrodinger operators
Absolutely continuous spectrum Schr¨odinger operator
2011/2/22
We observe that some special Itˆo diffusions are related to scattering properties of a Schr¨odinger operator on Rd, d 2. We introduce Feynman-Kac type formulae for these stochastic processes wh...
Schrodinger operators and the distribution of resonances in sectors
Schrodinger operators distribution of resonances
2011/2/22
The purpose of this paper is to give some refined results about the distribution of resonances in potential scattering. We use techniques and results from one and several complex variables, including ...
Symmetry preserving self-adjoint extensions of Schrödinger operators with singular potentials
Symmetry preserving self-adjoint extensions Schrö dinger operators singular potentials
2011/1/21
We develop a general technique for finding self-adjoint extensions of a symmetric operator that respect a given set of its symmetries. Prob-lems of this type naturally arise when considering two- and ...
Rescaled Mourre's commutator theory, application to Schrödinger operators with oscillating potential
Mourre’s commutator theory Mourre estimate limiting absorption principle
2011/1/18
We present a variant of Mourre’s commutator theory. We apply it to prove the limiting absorption principle for Schr¨odinger operators with a perturbedWigner-Von Neumann potential at suitable energies....
Square functions associated to Schrodinger operators
Schr¨odinger operator reverse H¨older class Littlewood-Paley square function
2010/12/14
We characterize geometric properties of Banach spaces in terms of boundedness of square functions associated to general Schr¨odinger operators of the form L = − + V , where the
nonnegative pot...
On the spectrum of skew-shift Schrödinger operators
spectrum ergodic Schrodinger operators skew-shift
2010/11/30
I prove that the spectrum of a skew-shift Schrodinger operator contains larges interval in the semi-classical regime. In the semi-classical limit,these intervals approach the range of the potential.
This paper deals with the existence,uniqueness,approximate solutions and errorsvaluation theorems concerning a class of nonlinear selfcontrolled systems with heredi-tary and polywave or polyvibrating ...
