Abstract

We investigate the padded version of reduction, an extension of multifraction reduction as defined in arXiv:1606.08991 (to appear), and connect it both with ordinary reduction and with the so-called Property H. As an application, we show that all Artin--Tits groups of sufficiently large type satisfy a weakening Conjecture A(padded) of Conjecture A, thus showing that the reduction approach is relevant for these groups.
