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 $${\displaystyle G\cdot x}$$: The defining properties of a group guarantee that the … 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 … See more Let $${\displaystyle G}$$ be a group acting on a set $${\displaystyle X}$$. 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 WebThis metric is not invariant under the diagonal action of C *, so we are unable to directly push it down to CP n in the quotient. However, this metric is invariant under the diagonal action of S 1 = U(1), the group of rotations.
