Abstract:
We investigate a principal $G$-bundle with $G$-invariant Riemannian metric on its total space. We derive formulas describing the Levi–Civita connection and curvatures in two-dimensional directions. We obtain estimates of the influence of properties of sectional curvatures to topological invariants of the bundle.
Keywords:
principal bundle, $G$-connection, Riemannian manifold, Levi–Civita connection, sectional curvature.
