Theorems about expansions of complete ultrametric and ultrauniform spaces are proved. Absolute polyhedral expansions and inverse mapping systems of expansions for non-complete spaces are investigated. This article also contains results about a relation of $dim (X)$ and dimensions of polyhedra over $\bf L$.39 pages, latexAlgebraic Topologytext
