**Representations of Groups: A Computational Approach **

The illustration conception of finite teams has obvious swift progress in recent times with the improvement of effective algorithms and machine algebra structures. this is often the 1st publication to supply an advent to the normal and modular illustration idea of finite teams with detailed emphasis at the computational features of the topic.

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

This is often the second one of 3 volumes dedicated to straightforward finite p-group concept. just like the 1st quantity, countless numbers of significant effects are analyzed and, in lots of instances, simplified. vital issues awarded during this monograph comprise: (a) category of p-groups all of whose cyclic subgroups of composite orders are basic, (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) class of p-groups all of whose subgroups of index pÂ² are abelian, (h) type of 2-groups all of whose minimum nonabelian subgroups have order eight, (i) p-groups with cyclic subgroups of index pÂ² are labeled.

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

George Mackey used to be a rare mathematician of significant strength and imaginative and prescient. His profound contributions to illustration conception, harmonic research, ergodic thought, and mathematical physics left a wealthy legacy for researchers that maintains this day. This e-book is predicated on lectures provided at an AMS unique consultation held in January 2007 in New Orleans devoted to his reminiscence.
