We show that$\beta_{j}^{X}$ is injective for $j=0$ and $j=1$. The case$j=3...  作者：Paul Balmer , Michel Matthey 来源：[J].Homology, Homotopy and Applications(IF 0.433), 2006, Vol.8 (1), pp.211-242 摘要：We establish a general method to produce cofibrant approximations in the modelcategory U S (C,D) of S -valued C -indexed diagrams with D -weakequivalences and D -fibrations. We also present explicit examples of suchapproximations. Here, S is an arbitrary cofibrantly g...  作者：Michel Matthey , Hervé Oyono-Oyono 来源：[J].Bulletin of the Belgian Mathematical Society - Simon Stevin(IF 0.316), 2003, Vol.10 (4), pp.525-535 摘要：The compatibility up to sign of the product structures inalgebraic$K$-theory and in topological$K$-theory of unitalBanach algebras is established in total degree$\leq 2\$\,.This answers a question posed by Milnor.
