Rationally trivial quadratic spaces are locally trivial:III
It is proved the following. Let R be a regular semi-local domain containing a field such that all the residue fields are infinite. Let K be the fraction field of R. If a quadratic space (R, q : R → R) over R is isotropic over K, then there is a unimodular vector v ∈ R such that q(v) = 0. If char(R) = 2, then in the case of even n we assume that q is a non-singular space in the sense of [Kn] and...
متن کاملGroups and spaces with all localizations trivial
The genus of a finitely generated nilpotent group G is defined as the set of isomorphism classes of finitely generated nilpotent groups K such that the p-localizations Kp, Gp are isomorphic for all primes p [19]. This notion turns out to be particularly relevant in the study of non-cancellation phenomena in group theory and homotopy theory. In the above definition, the restriction of finite gen...
متن کاملThe First Betti Numbers of Certain Locally Trivial Fibre Spaces
The purpose of this department is to provide early announcement of significant new results, with some indications of proof. Although ordinarily a research announcement should be a brief summary of a paper to be published in full elsewhere, papers giving complete proofs of results of exceptional interest are also solicited. Manuscripts more than eight typewritten double spaced pages long will no...
متن کاملSpaces with Finitely Many Non-trivial Homotopy Groups
It is well known that the homotopy category of connected CW-complexes X whose homotopy groups n;(X) are trivial for i> 1 is equivalent to the category of groups. One of the objects of this paper is to prove a similar equivalence for the connected CW-complexes X whose homotopy groups are trivial for i > n + 1 (where n is a fixed non-negative integer). For n = 1 the notion of crossed module inven...
متن کاملHow Trivial Is Trivial
This question is, I feel, in the same kind of idiot category as how long is a piece of string? interviewed recently by a journalist planning to write an article about the women (like me) who conduct 'Auntie' columns in women's magazines, I was asked what proportion of the letters I received each week could be labelled trivial. Her eyebrows shot up when I said that in my view, no human problem w...
