Abstract This article is dedicated to the surjective stability of the K1-functor for Chevalley groups for the embedding D5 into E6. This case was already studied by Plotkin. In this article, we improve his result by showing that surjective stability holds under a weaker assumption on a ring. Another result of this article shows how the K1-stability can help to study overgroups of subsystem subgroups. 
Bounded reduction of orthogonal matrices over polynomial rings
We prove that a matrix from the split orthogonal group over a polynomial ring with coefficients in a small-dimensional ring can be reduced to a smaller matrix by a bounded number of elementaryExpand

Surjective stability for the K1-functor for some exceptional chevalley groups
Proofs are given for results on surjective stability for the K1-functor for some exceptional Chevalley groups of normal types. Conditions are given (in terms of absolute stable rank) for stabilityExpand
Stability for Hermitian K1
The general Hermitian group GH2n and its elementary subgroup EH2n are the analogs in the theory of Hermitian forms of the general linear group GLn and its elementary subgroup En. This article provesExpand
Stabilization theorem for the Milnor K2-functor
Let Λ be an associative ring. For every natural number n there is a canonical homomorphismψn: K2,n(Λ)→K2(Λ), where K2 is the Milnor functor and K2,n(Λ) the associated unstable K-group. Dennis andExpand
ON THE STABILIZATION OF THE GENERAL LINEAR GROUP OVER A RING
We are concerned with the theory of matrix determinants (more precisely, the Whitehead determinant) over any associative ring from the algebraic point of view, i.e. K1-theory. The main goal of theExpand
Algebraic K-theory
The idea will be to associate to a ring R a set of algebraic invariants, Ki(R), called the K-groups of R. We can even do a little better than that: we will associated an (infinite loop) space K(R) toExpand
A third look at weight diagrams
In this paper, which is a sequel of [PSV], we develop a completely elementary approach to calculations in Chevalley groups G = G(O, R) of types 0 = E6 and E7 over a commutative ring using only theExpand

We obtain new results on the freeness of projective modules over polynomial rings. In particular we prove the freeness of all projective modules over polynomial rings in five variables withExpand
STABILIZATION OF UNITARY AND ORTHOGONAL GROUPS OVER A RING WITH INVOLUTION
Orthogonal and unitary groups over an associative ring with involution are examined. Using these groups, orthogonal and unitary K1-functors are introduced which are similar to general K1-functorsExpand

A universal central extension of a group G is a central extension, G, of G satisfying the additional conditions (i) G = [G, G], and (ii) every central extension of G is split. If, by analogy withExpand
