I want to show that there are one or two places in homotopy theory where we strongly suspect that there is something systematic going on, but where we are not yet sure what the system is. The first question concerns the stable J-homomorphism. I recall that this is a homomorphism J: ~ (SQ) ~ ~S = ~ + (Sn), n large. r r r n It is of interest to the differential topologists. Since Bott, we know that ~ (SO) is periodic with period 8: r 6 8 r = 1 2 3 4 5 7 9· . · Z o o o z On the other hand, ~S is not known, but we can nevertheless r ask about the behavior of J. The differential topologists prove: 2 Th~~: If I‘ = ~ - 1, so that ‘IT"r(SO) ~ 2, then J(‘IT"r(SO)) = 2m where m is a multiple of the denominator of ~/4k th (l. being in the Pc Bepnoulli numher.)

Q9njecture Eo If I‘ = 8k or 8k + 1, so that ‘IT"r(SO) = Z2‘ then J(‘IT"r(SO)) = 2 , 2 status of conjecture: Probably provable, but this is work in progl‘ess. | | 出版日期 | Book 19641st edition | | 關(guān)鍵詞 | Division; Homological algebra; Homotopie; Homotopy; Morphism; behavior; homomorphism; homotopy theory; proof | | 版次 | 1 | | doi | https://doi.org/10.1007/978-3-662-15942-2 | | isbn_ebook | 978-3-662-15942-2Series ISSN 0075-8434 Series E-ISSN 1617-9692 | | issn_series | 0075-8434 | | copyright | Springer-Verlag Berlin Heidelberg 1964 |
