Definition 1.13 The centralizer C G (q) of an element q in G is the set of all elements g G that commute with q. That is: C G (q) ={g G : gq = qg, for some q G}. This is a subgroup of G and the index of C G (q) in G is the size of the conjugacy class C(q) of q in G. That is |C(q)| = |G : C G (q)|. In particular |C(q)| divides |G|. If q is a central element q

Definition, We de ne the center of a group G as Z(G) = C G(G) and note that it is the set of elements of G which commute with all other elements. ,Definition, Given a group G and ;6= A G, we de ne for g 2G, gAg 1 = fgag 1 j a 2Ag. Further, we de ne the normalizer of A in G to be N G(A) = fg 2G j gAg 1 = Ag.

Casing Centralizers: Are We Using Too Many or Too Few ...

Casing centralizer is a mechanical device secured around the casing at various locations to keep casing from contacting the wellbore walls. As a result of casing centralization, a continuous annular clearance around casing allows cement to completely seal the casing to the borehole wall.
