  • Feedback Equivalence of 1-dimensional Control Systems of the 1-st Order 
    Lychagin, V.V. (2009)
    The problem of local feedback equivalence for 1-dimensional control systems of the 1-st order is considered. The algebra of differential invariants and criteria for the feedback equivalence for regular control systems are found.
  • Hyperplanar Webs and Euler Equations 
    Goldberg, V.V.; Lychagin, V.V. (2009)
    We find necessary and sufficient conditions for the foliation defined by level sets of a function f(x1, . . . , xn) to be totally geodesic in a torsion-free connection and apply them to find the conditions for d-webs of ...
