Let u2Gbe a unipotent ,element,, and let A(u) = C G(u)=Co G (u) be the group of components (“component group”) of the ,centralizer, of u. We are concerned with the structure of the group A(u) (more precisely: with its conjugacy classes). Consider the set of all triples (1) (L;tZo;u) where Lis a pseudo-Levi subgroup with center Z= Z(L), the ...

In the profile, the red lines indicate that the side force is acting upward and that the casing touches the upper side of the well. The blue lines indicate that the side force is acting downward and that the casing touches the lower side of the well.

The notion of a σ-skew subdiagram will be used to describe the centralizer of e. It corresponds to what Ginzburg called an out-subsetin [1], while a, skew subdiagram, corresponds to an in-subset. Example 1.4. We shall represent a, skew, diagram by boxes. For example, the following is a, skew, diagram which is centrally symmetric if (i,j)=(0,0): (i,j)

Define the setK = x∈Z(G) C ∧ G (x) (2.1)It is easy to check that K is a normal subgroup of G. Of course, if G is an abelian group, then K = Z ∧ (G). A useful property of K is the following.Lemma 2.9. Consider K in (2.1). Then G ≤ K.Proof. Let x be an ,element, of Z(G) and y, g …

Observe that, C (g) = C (< g >), i.e the centralizer of an element is the centralizer of the subgroup generated by it. Next observe that C (H) = C (H ¯) for any subgroup of H ⊂ G. This means that the centralizer of g is equal to the centralizer of < g > ¯. < g > ¯ is a compact abelian subgroup of G.
