This paper studies, for p a prime, rank one isolated -minimal subgroups P in finite group G . Such share many of the features minimal parabolic groups Lie type. The structure Y , normal closure O ( ) is determined where smallest subgroup such that / -group. We find if ? and = 1 then either Z simple type characteristic or ? 7 with given by an explicit list. Of particular note twenty four out six...

There are two basic theorems. Let G be a strong parapolar space with these three properties: (1) For each point x and symplecton S, x is collinear to some point of S. (2) The set of points at distance at most two from a point forms a geometric hyperplane. (3) If every symplecton has rank at least three, every maximal singular subspace has finite projective rank. Then G is either D6; 6;A5; 3 or ...

We begin with a quick summary of the notions of global singularity theory and the theory of Thom polynomials. For a more detailed review we refer the reader to [1, 15]. Let N and K be two complex manifolds of dimensions n and k respectively; assume that n ≤ k. Consider a holomorphic map f : N → K for which the differential d fp : TpN → TpK at a generic point p ∈ N is nonsingular, i.e. has rank ...

The sporadic simple group F2 known as Fischer's Baby Monster acts flag-transitively on a rank 5 P-geometry G(F2). P-geometries are geometries with string diagrams, all of whose nonempty edges except one are projective planes of order 2 and one terminal edge is the geometry of the Petersen graph. Let AC be a flag-transitive P-geometry of rank 5. Suppose that each proper residue of K is isomorphi...

Let R be a commutative Noetherian ring of dimension d and M cancellative torsion-free seminormal monoid. Then: (1) A type R[d,m,n] P projective A[M]-module rank r≥max {2,d+1}. Then the action E(A[M]⊕P) on (A[M]⊕P) is transitive (2) Assume (R,m,K) regular local containing field k such that either char k=0 or k=p tr-deg K∕
