For an abelian group $A$, we give a precise homological description of the kernel of the natural map $Gamma(A) to Aotimes_mathbb{Z} A$, $gamma(a)mapsto aotimes a$, where $Gamma$ is whiteheads quadratic functor from the category of abelian groups to itself.

We provide a more economical refined version of Evrards categorical cocylinder factorization of a functor [Ev1,2]. We show that any functor between small categories can be factored into a homotopy equivalence followed by a (co)fibred functor which sa
tisfies the (dual) assumption of Quillens Theorem B.
In this paper the third homology group of the linear group GL_2(R) with integral coefficients is investigated, where R is a commutative ring with many units.
The K-theory of a functor may be viewed as a relative version of the K-theory of a ring. In the case of a Galois extension of a number field F/L with rings of integers A/B respectively, this K-theory of the norm functor is an extension of a subgroup
of the ideal class group Cl(A) by the 0-Tate cohomology group with coefficients in A*. The Mayer-Vietoris exact sequence enables us to describe quite explicitly this extension which is related to the coinvariants of Cl(A) under the action of the Galois group. We apply these ideas to find results in Number Theory, which are known for some of them with different methods.
We observe that Whiteheads lemma is an immediate consequence of Stallings folds.
We present a short, self-contained, and purely combinatorial proof of Linniks theorem: for any $varepsilon > 0$ there exists a constant $C_varepsilon$ such that for any $N$, there are at most $C_varepsilon$ primes $p leqslant N$ such that the least p
ositive quadratic non-residue modulo $p$ exceeds $N^varepsilon$.
