Geometric Approach to Goursat Flags
A Goursat flag is a chain Ds ⊂ Ds−1 ⊂ D1 ⊂ D0 = TM of subbundles of the tangent bundle TM such that corank Di = i and Di−1 is generated by the vector fields in Di and their Lie brackets. Engel, Goursat, and Cartan studied these flags and established a normal form for them, valid at generic points of M . Recently Kumpera, Ruiz and Mormul discovered that Goursat flags can have singularities, and ...
متن کاملA Monster Tower Approach to Goursat Multi-flags
We consider the problem of classifying the orbits within a tower of fibrations with P-fibers that generalize the Monster Tower due to Montgomery and Zhitomirskii. The action on the tower is given by prolongations of diffeomorphism germs of 3-space. As a corollary we give the first steps towards the problem of classifying Goursat 2-flags of small length. In short, we classify the orbits within t...
متن کاملOn local classi cation of Goursat structures
Goursat structures are the dual objects of E. Cartan's \special" systems (also called \en drapeau" in 7]). We prove that the growth vector is not a complete local invariant for a Goursat structure on R n , n 9; and that there exist innnitely many locally non-equivalent Goursat structures on R n , n 10. Sur la classiication locale des structures de Goursat Les structures de Goursat sont les obje...
متن کاملClassification of real moduli spaces over genus 2 curves
We classify, in terms of simple algebraic equations, the fixed point sets of the moduli space of stable bundles over genus 2 curves with anti-holomorphic involutions. 1991 MS Classification: 14H60, 51M30.
