    The Riemann-Hilbert approach for the equations PIII(D6) and PIII(D7) is studied in detail, involving moduli spaces for connections and monodromy data, Okamoto-Painlevé varieties, the Painlevé property, special solutions ...
  • Geometric attractor of an electron beam passing through a crystal 
    Gurin, A.M. (Вопросы атомной науки и техники, 2001)
    The Lemmlein algorithm assigns a cyclic interaction of a mathematical point with other (n+1) points of the n - dimensional Euclidean space. In this paper generalization A of the Lemmlein algorithm for an arbitrary number ...
  • Geometric characteristics of quantum evolution: curvature and torsion 
    Laba, H.P.; Tkachuk, V.M. (Condensed Matter Physics, 2017)
    We study characteristics of quantum evolution which can be called curvature and torsion. The curvature shows a deviation of the state vector in quantum evolution from the geodesic line. The torsion shows a deviation ...

    Andreev, P.D. (Журнал математической физики, анализа, геометрии, 2009)
    The procedures of gluing and the Hausdorff limit in the class of metric spaces nonpositively curved in the sense of Busemann are studied in the paper. Conditions under which the resulting spaces belong to the same class are found.
