An algorithm for the construction of parametrizing bimodules for homogeneous module

We give an algorithmic description of matrix bimodules parametrizing all indecomposable homogeneous Λ-modules with a fixed slope q over a tubular canonical algebra Λ, for all possible slopes q (Main Theorem 3.3). A crucial role in this description is played by universal extensions of bimodules and their nice properties (Theorems 3.1 and 3.2).
