Outer automorphism anomalies

نویسندگان

چکیده

We discuss anomalies associated with outer automorphisms in gauge theories based on classical groups, namely charge conjugations for $SU(N)$ and parities $SO(2r)$. emphasize the inequivalence (yet related by a flavor transformation) between two versions of conjugation $SU(2k)$, $SO(2r)$, $E_6$ symmetries. The subgroups that commute are identified. Some can lead to paradox, which is resolved observation they anomalous hence not then anomaly matching conditions involve or parities. Interesting examples given where spontaneously broken.

Kazhdan Groups with Infinite Outer Automorphism Group

For each countable group Q we produce a short exact sequence 1 → N → G → Q → 1 where G is f.g. and has a graphical 1 6 presentation and N is f.g. and satisfies property T . As a consequence we produce a group N with property T such that Out(N) is infinite. Using the tools developed we are also able to produce examples of nonHopfian and non-coHopfian groups with property T . One of our main tool...

Outer Automorphism Groups of Bieberbach Groups

Let Γ be a Bieberbach group it is a fundamental group of a flat manifold. In this paper we give necessary and sufficient conditions on Out(Γ) to be infinite. We also compare our result with the previous one ([8], Theorem 7.1) about Anosov automorphisms of flat manifolds. We give several examples of Bieberbach groups.

On Outer Automorphism Groups of Coxeter Groups

It is shown that the outer automorphism group of a Coxeter group W of nite rank is nite if the Coxeter graph contains no innnite bonds. A key step in the proof is to show that if the group is irreducible and 1 and 2 any two bases of the root system of W, then 2 = w 1 for some w 2 W. The proof of this latter fact employs some properties of the dominance order on the root system introduced by Bri...

The expansion factors of an outer automorphism and its inverse

A fully irreducible outer automorphism φ of the free group Fn of rank n has an expansion factor which often differs from the expansion factor of φ. Nevertheless, we prove that the ratio between the logarithms of the expansion factors of φ and φ is bounded above by a constant depending only on the rank n. We also prove a more general theorem applying to an arbitrary outer automorphism of Fn and ...

Outer automorphism groups of some ergodic equivalence relations

Let R a be countable ergodic equivalence relation of type II1 on a standard probability space (X,μ). The group Out R of outer automorphisms of R consists of all invertible Borel measure preserving maps of the space which map R-classes to R-classes modulo those which preserve almost every R-class. We analyze the group Out R for relations R generated by actions of higher rank lattices, providing ...
