• Total mean curvature surfaces in the product space S^n x R and applications 

      Albujer, Alma L.; Ferreira da Silva, Sylvia; Reis dos Santos, Fábio R. (Cambridge University Press, 2023)
      The total mean curvature functional for submanifolds into the Riemannian product space S^n × R is considered and its first variational formula is presented. Later on, two second order differential operators are defined and ...
    • Willmore surfaces and Hopf tori in homogeneous 3-manifolds 

      Albujer, Alma L.; Santos, Fábio R. dos (Springer, 2022)
      Some classification results for closed surfaces in Berger spheres are presented. On the one hand, a Willmore functional for isometrically immersed surfaces into an homogeneous space E3(κ,τ) with isometry group of dimension ...
