Pseudospherical surfaces with singularities

D Brander - Annali di Matematica Pura ed Applicata (1923-), 2017 - Springer
We study a generalization of constant Gauss curvature-1-1 surfaces in Euclidean 3-space,
based on Lorentzian harmonic maps, that we call pseudospherical frontals. We analyse the …

Maximal surfaces in the Lorentzian Heisenberg group

D Brander, S Kobayashi - arXiv preprint arXiv:2302.10559, 2023 - arxiv.org
The 3-dimensional Heisenberg group can be equipped with three different types of left-
invariant Lorentzian metric, according to whether the center of the Lie algebra is spacelike …

Cuspidal edges with the same first fundamental forms along a knot

A Honda, K Naokawa, K Saji, M Umehara… - Journal of Knot Theory …, 2020 - World Scientific
Letting C be a compact C ω-curve embedded in the Euclidean 3-space (C ω means real
analyticity), we consider a C ω-cuspidal edge f along C. When C is non-closed, in the …

The flow-geodesic curvature and the flow-evolute of spherical curves

M CRASMAREANU - Turkish Journal of Mathematics, 2024 - journals.tubitak.gov.tr
We introduce and study a deformation of the geodesic curvature for a given spherical curve
γ. Also, wedefine a new type of evolute and two Fermi-Walker type derivatives for γ. Some …

Rigidity of minimal Lagrangian diffeomorphisms between spherical cone surfaces

C El Emam, A Seppi - Journal de l'École polytechnique …, 2022 - numdam.org
We prove that any minimal Lagrangian diffeomorphism between two closed spherical
surfaces with cone singularities is an isometry, without any assumption on the multiangles of …

Families of spherical surfaces and harmonic maps

D Brander, F Tari - Geometriae Dedicata, 2019 - Springer
We study singularities of constant positive Gaussian curvature surfaces and determine the
way they bifurcate in generic 1-parameter families of such surfaces. We construct the …
