Totally geodesic surfaces in the complex quadric

Autor: Marilena Moruz, Joeri Van der Veken, Luc Vrancken, Anne Wijffels

Publikováno v: Differential Geometry and Global Analysis. :153-161

We provide explicit descriptions of all totally geodesic surfaces of a complex quadric of arbitrary dimension. Totally geodesic submanifolds of complex quadrics were first studied by Chen and Nagano in 1977 and fully classified by Klein in 2008. In p

H-Umbilical Lagrangian Submanifolds of the Nearly Kähler \( {\mathbb{S}^3\times\mathbb{S}^3} \)

Autor: Miroslava Antić, Marilena Moruz, Joeri Van der Veken

Publikováno v: Mathematics, Vol 8, Iss 9, p 1427 (2020)

H-umbilicity was introduced as an analogue of total umbilicity for Lagrangian submanifolds since, in some relevant cases, totally umbilical Lagrangian submanifolds are automatically totally geodesic. In this paper, we show that, in the homogeneous ne

Geometric Study of Marginally Trapped Surfaces in Space Forms and Robertson-Walker Spacetimes—An Overview

Autor: Kristof Dekimpe, Joeri Van der Veken

Publikováno v: Axioms, Vol 9, Iss 2, p 60 (2020)

A marginally trapped surface in a spacetime is a Riemannian surface whose mean curvature vector is lightlike at every point. In this paper we give an up-to-date overview of the differential geometric study of these surfaces in Minkowski, de Sitter, a

Minimal Lagrangian submanifolds of the complex hyperquadric

Autor: Luc Vrancken, Joeri Van der Veken, Xianfeng Wang, Hui Ma, Haizhong Li

Publikováno v: Science China Mathematics. 63:1441-1462

We introduce a structural approach to study Lagrangian submanifolds of the complex hyperquadric in arbitrary dimension by using its family of non-integrable almost product structures. In particular, we define local angle functions encoding the geomet

The Bonnet problem for harmonic maps to the three-sphere

Autor: Bart Dioos, Joeri Van der Veken

Publikováno v: Advances in Geometry. 19:335-343

In previous work [15] the authors defined transforms for non-conformal harmonic maps from a Riemann surface into the 3-sphere. An observation from that study was that two invariants, a real and a complex function, determine a non-conformal harmonic m

‘There’s always an option’: Collaborative Writing of Multilingual Interactive Fanfiction in a Foreign Language Class

Autor: Shannon Sauro, Judith Buendgens-Kosten, Joeri Van der Veken, Frederik Cornillie

In the digital wilds, thriving storytelling practices (often in transcultural and multilingual contexts) share with Maker culture a belief in learning through doing, bricolage, collaboration, and playfulness. Key examples are fanfiction, a form of cr

Tensor completion using geodesics on Segre manifolds

Autor: Lars Swijsen, Joeri Van der Veken, Nick Vannieuwenhoven

We propose a Riemannian conjugate gradient (CG) optimization method for finding low rank approximations of incomplete tensors. Our main contribution consists of an explicit expression of the geodesics on the Segre manifold. These are exploited in our
