Essay

We describe the structure of the exponent matrix of a semi-maximal ring. A classification of tiled orders, which have quivers with two or three vertices, is obtained. We obtain sufficient conditions on an orgraph under which it is (or can't be) the quiver of a tiled order. Necessary and sufficient conditions on a quiver of a tiled order under which this order is triangular are obtained. All simple orcycles of the quiver of a triangular order are described.
