A geometric approach to free left modules over right Bezout domains
Within a lattice-geometric frame, the author gives a characterization of free left modules of rank \(\geq 4\) over right Bezout domains. Results of this kind have been obtained for torsion-free left modules over left Ore domains by \textit{U. Brehm} [Rings and geometry, Proc. NATO Adv. Study Inst., Istanbul/Turkey 1984, NATO ASI Ser., Ser. C 160, 511-550 (1985; Zbl 0673.06005)].
