Extensions of linking systems and fusion systems

Bob Oliver

Abstract:
We correct two errors in the statement and proof of a theorem in 
\cite{BCGLO2}, and at the same time extend that result to a more general 
theorem about extensions of $p$-local finite groups.  Other special cases 
of this theorem have already been shown in two later papers, so we feel it 
will be useful to have this more general result in the literature.
