a note on the affine subgroup of the symplectic group
we examine the symplectic group $sp_{2m}(q)$ and its correspondingaffine subgroup. we construct the affine subgroup and show that itis a split extension. as an illustration of the above we study theaffine subgroup $2^5{:}sp_4(2)$ of the group $sp_6(2)$.
متن کاملCremona Transformations, Surface Automorphisms and the Group Law
We give a method for constructing many examples of automorphisms with positive entropy on rational complex surfaces. The general idea is to begin with a quadratic cremona transformation that fixes some cubic curve and then use the group law to understand when the indeterminacy and exceptional behavior of the transformation may be eliminated by repeated blowing up.
متن کاملOn Marginal Automorphisms of a Group Fixing the Certain Subgroup
Let W be a variety of groups defined by a set W of laws and G be a finite p-group in W. The automorphism α of a group G is said to bea marginal automorphism (with respect to W), if for all x ∈ G, x−1α(x) ∈ W∗(G), where W∗(G) is the marginal subgroup of G. Let M,N be two normalsubgroups of G. By AutM(G), we mean the subgroup of Aut(G) consistingof all automorphisms which centralize G/M. AutN(G) ...
متن کاملA Note on Cremona Transformations
In 1883 Kantor' stated and attempted a demonstration of a theorem which asserted that the satisfaction of a system of equations by a certain set of positive integers was sufficient to assure that these integers would represent a planar Cremona transformation. Since then the theorem has been repeated several times in the literature. Recently Coolidge2 attached new significance to the theorem and...
متن کاملBlanc Conjugacy classes of affine automorphisms of K n and linear automorphisms of P n in the Cremona groups
Let K be an algebraically closed field of characteristic 0 and let K and P denote respectively the affine and projective n-spaces over K. The Cremona group, which is the group of birational maps of these two spaces,Bir(K) = Bir(P), has been studied a lot, especially in dimension 2 and 3, see for example [Hud] and [AlC]. Its subgroup of biregular morphisms (or automorphisms) of K, called the aff...
