We study the target-space duality transformations in p--branes as
transformations which mix the worldvolume field equations with Bianchi
identities. We consider an (m+p+1)-dimensional spacetime with p+1
dimensions compactified, and a particular form of the background fields. We
find that while a GL(2)=SL(2)ΓR group is realized when m=0, only a
two parameter group is realized when m>0.Comment: 12 pages, plain TEX, SISSA 44/94/EP, CTP-TAMU-15/9
