  • Global rotation estimation using weighted iterative lie algebraic averaging 
    Reich, Martin; Heipke, Christian (Göttingen : Copernicus GmbH, 2015)
    In this paper we present an approach for a weighted rotation averaging to estimate absolute rotations from relative rotations between two images for a set of multiple overlapping images. The solution does not depend on ...
  • Hidden symmetries of deformed oscillators 
    Krivonos, Sergey; Lechtenfeld, Olaf; Sorin, Alexander (Amsterdam : Elsevier B.V., 2017)
    We associate with each simple Lie algebra a system of second-order differential equations invariant under a non-compact real form of the corresponding Lie group. In the limit of a contraction to a Schrödinger algebra, these ...
