(PDF) Virtually free pro-p groups whose torsion elements ...

Note that the same example is valid for abstract groups. Lemma 5.1 Let A ∼ = B = ,S3, be the symmetric group on a 3-element set and C := C2 . Form the amalgamated free profinite product G = A ∐C B, where C identifies with given 2-Sylow subgroups in A and B respectively. Then for every torsion element t ∈ G its ,centralizer, is finite.

FROM A 3-LOCAL PLUS 3-FUSION TO THE CENTRALIZER OF AN ...

TO ,THE CENTRALIZER, OF AN INVOLUTION DANIEL FROHARDT Abstract. It is shown that much of the structure of ,the centralizer, of a central involution in a group of characteristic 2 type with a standard 3-component of type GL(n, 2), n > 6, is easily determined from the 3-fusion. Consequently, one can

DISTRIBUTTVELY GENERATED CENTRALIZER NEAR-RINGS

[4]. There we considered the question "When is a ,centralizer, near-ring a ring?". It was found that the only rings that occur as ,centralizer, near-rings 6(6?; G), 6? a group of automorphisms of G, are direct sums of fields. In the d.g. case we ,find, a similar situation when G is a solvable group. In this special case in which 6(6?; G) is d.g. we

How to show that C(a) is a subgroup of G if G be a group ...

You're asking about ,the centralizer, of a, defined as the set of all elements of G that commute with a. To show that it's a subgroup, first prove that it contains the identity element. Then show that if x and y both belong to C ( a), ( x − 1 y) a = a ( x − 1 y) That will give you the other properties of the group.

Chapter 13

To ,find, generators for ,the centralizer,, we go via so-called standard generators. They have been introduced by Wilson [12] to give a unified treatment in the computational theory of sporadic simple groups. Standard generators are sets of elements that are relatively easy to ,find,, with only a small number of defining relations.
