The gluing problem in the fusion systems of the symmetric
and alternating groups

Abstract. A solution to Linckelmann's gluing problem in
all fusion systems of blocks yields and alternative 
formulation of Alperin's weight conjecture. Using Bredon 
equivariant cohomology techniques we solve the gluing 
problem in fusion systems that are isomorphic to the
fusion systems of the symmetric groups or, for odd
primes, the alternating groups.
