G2: (n+m)+e = n+(m+e); associative
G3: n+0=0 neutral
G4: n+e=0 inverse - 5When two groups are homomorphic? Isomorphic?Home is a map that preserves selected structure between two algebraic structures.
Isomo is a home that is the inverse - 6What is symmetryIs the invariance with respect to a group of transformations i.e. triangle example
- 7What is a symmetry group? Why is it important?G={C3,C3^2,E}
Is the group of all transformations under which the object is invariant with composition as the group operation.
All the laws of nature originates in symmetries. Symmetries of the laws of physics determine the properties of the parishes found in nature - 8What is group representation?
