Research Abstract	The notion of a category with an action of a group G - a G-category - is needed to make algebraic K-theory equivariant one. Though various notions have been used so far, the relations between these notions don't have been explained explicitly yet. I dealed uniformly with the notions of G-categories and established the comparison in the complete form by introducing the notion of a g-category from the point of view of galois descent in linear categories. It's important to consider simultaneously the limit categories together with G-categories and G-functors because of my philospohy "equivariant = Galois descent". The objects to appear are as follows. ([.zu.]) I also refer to exact G-categories and Q-construction induction theory etc.
