Darboux transforms of Dupin surfaces

Emilio Musso, Lorenzo Nicolodi (2002)

Banach Center Publications

We present a Möbius invariant construction of the Darboux transformation for isothermic surfaces by the method of moving frames and use it to give a complete classification of the Darboux transforms of Dupin surfaces.

Darboux-Zwangläufe und äquiforme Kinematik

Otto Röschel (1991)

Applications of Mathematics

In dieser Arbeit werden Yusammensetzungen euklidischer Darboux - Zwangläufe mit rastfesten zentrischen Ähnlichkeiten studiert. Bei den so entstehenden zweiparametrigen äquiformen Bewegungsvorgängen werden die Punkte einer besonderen gangfesten Fläche dritter Ordnung φ in Bahnebenen geführt, während allgemeine Punkte des Gangraumes an Kegel zweiter Ordnung gebunden sind. Weiters wird gezeigt, dass sich durch Spezialisierung innerhalb dieser zweiparametrigen Schar alle von A. Karger [2] angegeben...

De Lellis-Topping type inequalities for f-Laplacians

Guangyue Huang, Fanqi Zeng (2016)

Studia Mathematica

We establish an integral geometric inequality on a closed Riemannian manifold with ∞-Bakry-Émery Ricci curvature bounded from below. We also obtain similar inequalities for Riemannian manifolds with totally geodesic boundary. In particular, our results generalize those of Wu (2014) for the ∞-Bakry-Émery Ricci curvature.

De Rham cohomology and homotopy Frobenius manifolds

Vladimir Dotsenko, Sergey Shadrin, Bruno Vallette (2015)

Journal of the European Mathematical Society

We endow the de Rham cohomology of any Poisson or Jacobi manifold with a natural homotopy Frobenius manifold structure. This result relies on a minimal model theorem for multicomplexes and a new kind of a Hodge degeneration condition.

De Rham decomposition theorems for foliated manifolds

Robert A. Blumenthal, James J. Hebda (1983)

Annales de l'institut Fourier

We prove that if M is a complete simply connected Riemannian manifold and F is a totally geodesic foliation of M with integrable normal bundle, then M is topologically a product and the two foliations are the product foliations. We also prove a decomposition theorem for Riemannian foliations and a structure theorem for Riemannian foliations with recurrent curvature.
