چکیده
We solve the local Cauchy problem for the nonlinear Schrödinger equation with harmonic potential, an equation appearing in the study of Bose-Einstein condensation. We prove that the mathematical study of this equation is very close to the study of the same equation without potential, thanks to two explicit operators. We prove the analogue of the pseudo-conformal conservation law, and results for the global Cauchy problem or wave collapse.

We undertake a comprehensive study of the nonlinear Schrödinger equation iut +∆u = λ1|u| 1u+ λ2|u| 2u, where u(t, x) is a complex-valued function in spacetime Rt × Rx , λ1 and λ2 are nonzero real constants, and 0 < p1 < p2 ≤ 4 n−2 . We address questions related to local and global well-posedness, finite time blowup, and asymptotic behaviour. Scattering is considered both in the energy space H(R...

In this article we give an overview on some recent development of Littlewood-Paley theory for Schrödinger operators. We extend the LittlewoodPaley theory for special potentials considered in the authors’ previous work. We elaborate our approach by considering potential in C∞ 0 or Schwartz class in one dimension. In particular the low energy estimates are treated by establishing some new and ref...

In two dimensions the Gross-Pitaevskii equation for a cold, dilute gas of bosons has an energy dependent coupling parameter describing particle interactions. We present numerical solutions of this equation for bosons in harmonic traps and show that the results can be quite sensitive to the precise form of the coupling parameter that is used. Solutions of the Gross-Pitaevskii equation in two dim...

Bushes of normal modes represent exact mathematical objects describing specific dynamical regimes in nonlinear mechanical systems with point or space symmetry. In the present paper, we outline the bush theory and illustrate it with some bushes of small dimensions in octahedral mechanical structures.

We present a unified approach for obtaining global a priori estimates for solutions of nonlinear defocusing Schrödinger equations with defocusing nonlinearities. The estimates are produced by contracting the local momentum conservation law with appropriate vector fields. The corresponding law is written for defocusing equations of tensored solutions. In particular, we obtain a new estimate in t...
