These inner automorphisms form a
subgroup of the
automorphism group, and the
quotient of the
automorphism group by this
subgroup is defined...

subgroups are
conjugate by an
inner automorphism, so to
study outer automorphisms it
suffices to
consider automorphisms that fix a
given Borel subgroup....

automorphisms are
outer automorphisms. Non-abelian
groups have a non-trivial
inner automorphism group, and
possibly also
outer automorphisms. Group...
- In mathematics, the
automorphism group of an
object X is the
group consisting of
automorphisms of X
under composition of morphisms. For example, if X is...
