Local moduli in the special 2-flags of length 5
Piotr Mormul
A number of key issues concerning distributions generating 1-flags(most often called Goursat flags) has been settled over the past 30 years. Presently similar questions are being d…
Symmetries of special 2-flags
Piotr Mormul, Fernand Pelletier
This work is a continuation of authors' research interrupted in the year 2010. Derived are recursive relations describing for the first time all infinitesimal symmetries of special…
Order of tangency between manifolds
Wojciech Domitrz, Piotr Mormul, Piotr Pragacz
We study the order of tangency between two manifolds of same dimension and give that notion three quite different geometric interpretations. Related aspects of the order of tangenc…
Small growth vectors of the compactifications of the contact systems on
Piotr Mormul
It is well known that the compactifications of the canonical contact systems living on real jet spaces , , are locally universal Goursat distributions, …
Special 2-flags in lengths not exceeding four: a study in strong nilpotency of distributions
Piotr Mormul, Fernand Pelletier
In the recent years, a number of issues concerning distributions generating 1- flags (called also Goursat flags) has been analyzed. Presently similar questions are discussed as reg…
Singularity Classes of Special 2-Flags
Piotr Mormul
In the paper we discuss certain classes of vector distributions in the tangent bundles to manifolds, obtained by series of applications of the so-called generalized Cartan prolonga…
