Dimension in Finite Baer ∗-Ringsof . require different techniques and are treated separately. A salient feature of the exposition is that virtually all results are obtained without assuming the parallelogram law (P); it is only in the final section on modularity (Section 34) that (P) is invoked.Silent-Ischemia 发表于 2025-3-26 17:48:21
