 +   <hidden TTP02-31  Bosonic Corrections to $\Delta r$ at the Two Loop Level > The details of the recent calculation of the two-loop bosonic 
 + corrections to the muon lifetime in the Standard Model are 
 + presented. The matching on the Fermi theory is 
 + discussed. Renormalisation in the on-shell and in the \MSb scheme is 
 + studied and transition between the schemes is shown to lead to 
 + identical results. High precision numerical methods are compared with 
 + mass difference and large mass expansions.
