 On the recent papers of Arnold

    (talk of V.M.Zakalyukin)

    -- First steps of local symplectic algebra
    -- First steps of local contact algebra


 Arnold classifies the simple singularities of curves
 in symplectic and contact spaces (up to the right-left
 group, preserving the corresponding structure in the
 target space)

    First examples shows the existence of new
 invariants.
    The technics used is based on  special
 structures in local algebras of singularities.
