Twisted Conjugacy Classes in Symplectic Groups, Mapping Class Groups and Braid Groups
We prove that the symplectic group Sp(2n,Z) and the mapping class group ModS of a compact surface S satisfy the R∞ property. We also show that Bn(S), the full braid group on n-strings of a surface S, satisfies the R∞ property in the cases where S is either the compact disk D, or the sphere S. This means that for any automorphism φ of G, where G is one of the above groups, the number of twisted ...
متن کاملCOMPUTING THE PRODUCTS OF CONJUGACY CLASSES FOR SPECIFIC FINITE GROUPS
Suppose $G$ is a finite group, $A$ and $B$ are conjugacy classes of $G$ and $eta(AB)$ denotes the number of conjugacy classes contained in $AB$. The set of all $eta(AB)$ such that $A, B$ run over conjugacy classes of $G$ is denoted by $eta(G)$.The aim of this paper is to compute $eta(G)$, $G in { D_{2n}, T_{4n}, U_{6n}, V_{8n}, SD_{8n}}$ or $G$ is a decomposable group of order $2pq$, a group of...
متن کاملSign conjugacy classes in symmetric groups
A special type of conjugacy classes in symmetric groups is studied and used to answer a question about odd-degree irreducible characters.
متن کاملCONJUGACY CLASSES IN FINITE p-GROUPS
Of course, in that problem we have to take into account that the class sizes impose restrictions on the group structure. E.g. if the sizes are {1, p}, then the nilpotency class has to be 2. More precisely: the class sizes of a p-group G are {1, p} iff |G′| = p (Knoche; see also Theorem 3 below). But we can ask, e.g., if, given any set S ≠ {1, p} of p-powers, does there exist a group of class 3 ...
متن کاملA Probabilistic Approach to Conjugacy Classes in the Finite Symplectic and Orthogonal Groups
Markov chains are used to give a purely probabilistic way of understanding the conjugacy classes of the finite symplectic and orthogonal groups in odd characteristic. As a corollary of these methods one obtains a probabilistic proof of Steinberg’s count of unipotent matrices and generalizations of formulas of Rudvalis and Shinoda.
