Abstract:
We examine the question when a group acting by cohomogeneity one on the base of a principal $\operatorname {G}$-bundle can be lifted to the total space and commutes with the action by $\operatorname {G}$. We answer this question completely when the base of the principle bundle is $4$-dimensional.References
