Аннотация: Diagonal direct limits of permutation groups are studied using their representations by homeomorphisms of the boundary of rooted trees.
We describe a new method of classification of such permutation groups, and use this method to find a complete classification of diagonal direct limits of symmetric and alternating groups up to isomorphisms.

Ключевые слова: locally finite simple groups, diagonal embeddings, direct limits, measure-preserving actions.
