Let E be a compact Lie group, G a closed subgroup of E, and H a closed normal subgroup of G. For principal fibre bundle (E,p, E/Gr and (E/H,p',E/G~G/H), the relation between autG(E) (resp. autG* (E)) and autG/H (E/H) (resp. autG/H* (E/H)) is investigated by using bundle map theory and transformation group theory. It will enable us to compute the group FG(E) (resp. EG(E)) while the group FG/H(E/H) is known. © 1998, Springer Verlag. All rights reserved.
