A 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 کاملGeometric 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 کاملSpelling Rules for the Monster/semple Tower
We further study the incidence relations that arise from the various subtowers, known as Baby Monsters, which exist within the R-Monster Tower. This allows us to complete the RV T class spelling rules. We also present a method of calculating the various Baby Monsters that appear within the Monster Tower.

متن کاملAn Elementary Approach to the Monster
is one of the most spectacular and mysterious mathematical achievements of the past fifty years. Unfortunately the various standard approaches to the Monster are notoriously difficult to learn. This paper presents a relatively elementary approach to the Monster. We describe a construction of the smallest non-Abelian finite simple group (of order 60), and show that it very closely parallels a co...
متن کاملA Novel Optimization Approach Applied to Multi-Pass Turning Process
Optimization of turning process is a non-linear optimization with constrains and it is difficult for the conventional optimization algorithms to solve this problem. The purpose of present study is to demonstrate the potential of Imperialist Competitive Algorithm (ICA) for optimization of multipass turning process. This algorithm is inspired by competition mechanism among imperialists and coloni...
