摘要:

This paper contains a list of intersections of all pairs of maximal subgroups in nonabelian simple groups of order less than 106excluding PSL(2,q3 for q > 9. To compute possible orders of intersections a computer was used.

摘要:

We prove that for n≥2, the length of every subgroup chain inSnis at most 2n-3. The proof rests on an upper bound for the order of primitive permutation groups, due to Praeger and Saxl. The result has applications to worst case complexity estimates for permutation group algorithms.

摘要:

LetXandYbe complex analytic manifolds of the same complex dimension, letpbe a point inT*X\{0} and letqbe a point inT*Y\{0}. Let ϵ (p) (resp. ϵ (q)) denote the graded ring of germs of micro-differential operators atp(resp.q). Supply ϵ (p) and ϵ (q) with a suitable and natural convergence structure. Let X: ϵ (p) ϵ → (q) be a continuous degree preserving ring isomorphism. We show that there exists a vector field ∂ tangent toXin a neighbourhood of л(q), a symplectic map ф defined on a conic open neighbourhood ofqto a similar neighbourhood ofpsuch thatfor an appropriate constantzand a suitable invertible elementA. in ϵ (q) of degree 0. Uniqueness of this result is discussed and a global version is also given. Here < ∂, ξ > denotes the duality betweenT(Y) andT*(Y). of do,(X) = 1, then this representation is canonical.
