Completing unimodular rows to invertible matrices

Research output: Contribution to journalArticlepeer-review


Using ideas of Suslin-Vaserštein we prove some results concerning completing a unimodular row to an invertible matrix. For example, if A is a polynomial ring over a field in any number of indeterminates, then any unimodular row over A of length m ≥ n + 2 in which appears a polynomial in n indeterminates is completable to a matrix in Em(A).
