From Mennicke symbols to Euler Class groups

Research output: Chapter in Book/Report/Conference proceedingConference contributionAcademicpeer-review


Bhatwadekar and Raja Sridharan have constructed a homomorphism from an orbit
set of unimodular rows to an Euler class group. We show under weaker assumptions
that a generalization of its kernel is a subgroup. Our tool is a partially defined operation
on the set of unimodular matrices with two rows.
