In mathematics, a group action on a space is a group homomorphism of a given group into the group of transformations of the space. Similarly, a group action on a mathematical structure is a group homomorphism of a group into the automorphism group of the structure. It is said that the group … See more Left group action If G is a group with identity element e, and X is a set, then a (left) group action α of G on X is a function $${\displaystyle \alpha \colon G\times X\to X,}$$ See more Consider a group G acting on a set X. The orbit of an element x in X is the set of elements in X to which x can be moved by the elements of G. The orbit of x is denoted by See more The notion of group action can be encoded by the action groupoid $${\displaystyle G'=G\ltimes X}$$ associated to the group action. The stabilizers of the … See more We can also consider actions of monoids on sets, by using the same two axioms as above. This does not define bijective maps and equivalence relations however.

The action is called faithful or effective if The action is called … See more • The trivial action of any group G on any set X is defined by g⋅x = x for all g in G and all x in X; that is, every group element induces the identity permutation on X. • In every group G, left multiplication is an action of G on G: g⋅x = gx for all g, x in G. This action is free … See more If X and Y are two G-sets, a morphism from X to Y is a function f : X → Y such that f(g⋅x) = g⋅f(x) for all g in G and all x in X. Morphisms of G-sets are also called equivariant maps or G-maps. The composition of two morphisms is again a morphism. … See more WebThe basic idea in a group action is that the elements of a group are viewed as permuta- tions of a set in such a way that composition of the corresponding permutations matches …
