Automorphisms play a crucial role in the study of smooth planes.
For the orientation-preserving conformal automorphisms the bound is 84g- 1.
Automorphisms of algebraic varieties, supervisor: Yuri Prokhorov.
This bound is due to the Hurwitz automorphisms theorem, which holds for all g>1.
Field automorphisms are important to the theory of field extensions, in particular Galois extensions.
In the cases of the rational numbers(Q) and the real numbers(R)there are no nontrivial field automorphisms.

The conformal mappings of the surface correspond to orientation-preserving automorphisms of the hyperbolic plane.
The 18 inner automorphisms provide rotation of the mirrors by multiples of 20°, and reflections.
Beyond simplicity, a further benefit of this convention is that diagram automorphisms are realized by Euclidean isometries of the diagrams.
The automorphisms of a cyclically ordered set may be identified with C2, the two-element group, of direct and opposite correspondences.
This graph is not vertex-transitive: the automorphisms group has one orbit on vertices of size 8, and one of size 4.
Diagram automorphisms in turn yield additional Lie groups and groups of Lie type, which are of central importance in the classification of finite simple groups.
