Detektory Arakiego-Haaga, teoria Mourre’a i problem asymptotycznej zupełności w algebraicznej teorii pól kwantowych
… ciągłego. Scattering theory describes the asymptotic evolution of systems of interacting particles. A key concept in this area is asymptotic completeness, which is well-understood in non relativistic quantum mechanics but remains a challenging problem in local relativistic quantum field …

Asymptotic stability and completeness in 2D nonlinear Schrodinger equation
In this thesis we obtained new results on the asymptotic stability of ground states of the nonlinear Schrödinger equation in space dimension two. Under our hypotheses, the result actually shows asymptotic completeness in the regime of small initial data, i.e. any small initial data evolves into a …

Existence and analyticity of many body scattering amplitudes at low energies
… these amplitudes exist, are continuous and that asymptotic completeness holds. Moreover, if potentials fall off exponentially we prove that these amplitudes can be meromorphically continued in the energy, with square root branch points at the 2 cluster thresholds.

Proving infeasibility in motion planning
… algorithms. For motion planning algorithms, completeness is a crucial and desirable attribute. A complete motion planner returns a plan when one exists and also reports failure when no plan exists. However, complete motion planning is challenging, and many approaches aim for weaker notions of …

Diophantine Approximation as Cosmic Censor for AdS Black Holes
… main result shows the existence, uniqueness and asymptotic completeness of finite energy scattering states on the interior of Reissner–Nordström. The past and future scattering states are represented as suitable traces of the solution ψ on the bifurcate event and Cauchy horizons. Finally, we …
