Tsukuda [Tsu01] has investigated the homotopy types of connected components of $\\Map(S^4,B\\SU(2))$. But unfortunately, the proof of Lemma 2.4 in [Tsu01] is not correct for $p=2$. In this paper, we give a complete proof. Moreover, we investigate the further divisibility of $\\epsilon_i$ defined in [Tsu01]. In [Tsu], it is shown that divisibility of $\\epsilon_i$ have some information about $A_i$-equivalence types of the gauge groups.", "revisions": [ { "version": "v1", "updated": "2011-01-22T10:57:39.000Z" } ], "analyses": { "keywords": [ "connected components", "homotopy types", "gauge groups", "equivalence types", "divisibility" ], "tags": [ "journal article" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable" } } }
