The terms in the Ringel-Hall product of preinjective Kronecker modules.
In the main result of the paper (Theorem 8) the authors describe the terms in the Ringel-Hall product of preinjective Kronecker modules. As an application they obtain in Corollary 9 (via Lemma 2) an explicit solution to the column completion challenge for pencils with only minimal indices for columns corresponding to preinjective modules and to the row completion challenge for pencils with only minimal indicies for rows corresponding to preprojective modules.
