Geometrical Equivalence and Action Type Geometrical Equivalence of Group Representations
Geometrical Equivalence, Group Representations, Action Type Geometrical
In the present work, we will see the defnition of geometrical equivalence between universal algebras (and specially, for groups), and so apply that concept to elements in the variety of all representations of groups over a fixed field. In that space, we consider pairs of equations in free representations (XKF(Y ); F(Y )), where X and Y are finite. After that, we will see another kind of geometrical equivalence: the action type geometrical equivalence, whose definition is very similar to the usual one, but in this case we consider only subsets of XKF(Y ) in the free representation (XKF(Y ); F(Y )), for finite X and Y. Here, we have two main objectives: the first is to study the different cases of geometrical equivalence and the second is to show an example which proves that we can not conclude the geometrical equivalence between two representations from their action type geometrical equivalence and the geometrical equivalence of their groups.
