AbstractAbstract
[en] A unique continuation theorem for Schroedinger operators is derived by means of an identity which is also important in the proof of the non-existence of eigenvalues of such operators

AbstractAbstract
[en] We study L2-solutions of (-Δ+V-E)ψ = 0 in Rn, n ≥ 2 and derive a sharp upper bound to lx0(ψ) in terms of x0, E and V under rather restrictive assumptions on V. We show for V smooth that an upper bound to lx0(ψ) implies an upper bound to the dimension of the eigenspace associated to E. 16 refs. (Authors)

AbstractAbstract
[en] Let s (lambda)=(1/2 i π) Log det(lambda) be the scattering phase for the Schroedinger operator. Then the phase s (lambda) admits an asymptotic expansion at high energies. With a trace formula, we specify the form of this expansion and establish trace identities which determine the eigenvalues of the Hamiltonian H from the scattering phase

Soit s (lambda)=(1/2 i π) Log det(lambda) la phase de diffusion pour l'operateur de Schroedinger. La phase s (lambda) admet un developpement asymptotique aux hautes energies. Avec une formule de trace, on precise la forme de ce developpement et on etablit des identites de trace determinant les valeurs propres de l'hamiltonien H a partir de la phase de diffusionOriginal Title

AbstractAbstract
[en] Proofs are given that the symmetry transformations preserving the radial form of the SOq(N) Schroedinger equation lead to matching conditions which are essentially the same as the classical ones. Power-law potentials are treated as illustrative examples. In particular, the N1-dimensional q-deformed Coulomb system is converted into a q-deformed harmonic oscillator acting again in N2=2(N1-1) space dimensions. We also found that q-deformed 1/N energy formulae are covariant under such transformations to first 1/N-order. (author)

AbstractAbstract
[en] We study the asymptotic behaviour of the solutions and the scattering theory for the non linear Schroedinger equation in Rsup(n), n>=2. In particular we prove that for n>=3, under suitable assumptions, all solutions are dispersive, which implies asymptotic completeness. The assumptions cover the case of a single power

On etudie le comportement asymptotique des solutions et la theorie de la diffusion pour l'equation de Schroedinger non lineaire dans Rsup(n), n>=2. On montre en particulier, pour n>=3 que sous des hypotheses convenables, toutes les solutions a donnees initiales dans H1 sont dispersives, ce qui entraine la completude asymptotique. Les hypotheses couvrent le cas d'une seule puissanceOriginal Title
