Representations of Groups: A Computational Approach

The illustration thought of finite teams has visible quick progress lately with the improvement of effective algorithms and desktop algebra structures. this is often the 1st booklet to supply an creation to the normal and modular illustration conception of finite teams with designated emphasis at the computational facets of the topic.

Groups of Prime Power Order Volume 2 (De Gruyter Expositions in Mathematics)

This can be the second one of 3 volumes dedicated to user-friendly finite p-group thought. just like the 1st quantity, hundreds of thousands of significant effects are analyzed and, in lots of circumstances, simplified. vital themes offered during this monograph contain: (a) category of p-groups all of whose cyclic subgroups of composite orders are general, (b) category of 2-groups with precisely 3 involutions, (c) proofs of Ward's theorem on quaternion-free teams, (d) 2-groups with small centralizers of an involution, (e) category of 2-groups with precisely 4 cyclic subgroups of order 2n > 2, (f) new proofs of Blackburn's theorem on minimum nonmetacyclic teams, (g) category of p-groups all of whose subgroups of index p² are abelian, (h) type of 2-groups all of whose minimum nonabelian subgroups have order eight, (i) p-groups with cyclic subgroups of index p² are categorised.

Group Representations, Ergodic Theory, and Mathematical Physics: A Tribute to George W. Mackey

George Mackey used to be a rare mathematician of serious strength and imaginative and prescient. His profound contributions to illustration thought, harmonic research, ergodic idea, and mathematical physics left a wealthy legacy for researchers that keeps this day. This ebook relies on lectures offered at an AMS targeted consultation held in January 2007 in New Orleans devoted to his reminiscence.

A polynomial P in some R,, is given. It is desired to produce ;I polynomial $ ( P ) such that P = $(P)modulo fl;;* and such that each niononiial of $ ( P ) has Property A . ( 1 ) Set Q equal to I-’.

This means that (3) is not fulfilled in r(m,a, K ) when k $ K . Thus, identity relation (3) is fulfilled in the group r(m,n, K ) that we constructed if and only if k E K . If we take as K the set of all prime numbers not equal to a given prime number I, then we find that relation ( 3 ) for k = 1 does not follow from the other identities in system ( 3 ) . The fact that the system of group identities ( 3 ) is irreducible implies immediately that a continuum exists of systems of group identities of the form ( 3 ) that are not pairwise equivalent.
