In 1972 Vaserstem [7] established a remarkable theorem about the group SL2 over a Dedekind ring A of arithmetic type with infinitely many units. This theorem, which will be the topic of our discussions, describes the possibility of generating certain subgroups of SL2(Ä) by associated elementary matrices. The subgroups G = G(/1,/2) considered depend on two nonzero ideals /i and 72 of A and consist of the matrices
