Willmore-Like Tori in Killing Submersions

Abstract: The first variation formula and Euler-Lagrange equations for Willmore-like surfaces in Riemannian 3-spaces with potential are computed and, then, applied to the study of invariant Willmore-like tori with invariant potential in the total space of a Killing submersion. A connection with generalized elastica in the base surface of the Killing submersion is found, which is exploited to analyze Willmore tori in Killing submersions and to construct foliations of Killing submersions made up of Willmore tori with cons… Show more

“…Now, for a given function τ ∈ C ∞ (B(ρ)) we construct the Killing submersion over B(ρ) with bundle curvature τ , π : M (ρ, τ ) → B(ρ). Recall that the existence of these Killing submersions was proved in [10] (see also [25]). Finally, we apply Theorem 3.1 to draw the conclusion.…”

“…A natural question that arises here concerns the existence of Killing submersions over a given surface B (with Gaussian curvature K B ) for a prescribed bundle curvature τ ∈ C ∞ (B). For arbitrary Riemannian surfaces B, existence has been proved in [10]. In particular, if the surface B happens to be simply connected then this result was already proven in [25].…”

“…Proposition 2.1. [2] Let M be a Riemannian surface and choose any r ∈ C ∞ (M). Then, there exists a Killing submersion over M with bundle curvature r. In particular, it can be chosen to have compact fibers.…”

“…From Theorem 1.1, by a case by case inspection, we easily deduce that a CMC proper biharmonic surface S in a Killing submersion E(G, r) with constant angle φ must be an Hopf tube, that is φ = π/2. 2…”

“…Motivated by this fundamental fact, Killing submersions with 2-dimensional base and 1-dimensional fiber are now actively studied in differential geometry (see e.g. [9], [18], [33], [48]). It should be emphasize that Killing submersions with 2-dimensional base and 1-dimensional fiber involve geometrically natural dynamical systems -magnetic trajectories.…”
