Abstract: | We relate in a novel way the modular matrices of GKO diagonal cosets without fixed points to those of WZNW tensor products. Using this we classify all modular invariant partition functions ofsu(3)
k
su(3)1/su(3)
k+1
for all positive integer levelk, andsu(2)
k
su(2)
l
/su(2)
k+1
for allk and infinitely manyl (in fact, for eachk a positive density ofl). Of all these classifications, only that forsu(2)
k
su(2)1/su(2)
k+1
had been known. Our lists include many new invariants.Supported in part by NSERC. |
