On Jacobi fields and canonical connection in sub-Riemannian geometry [PDF]

open access: yes, 2017
In sub-Riemannian geometry the coefficients of the Jacobi equation define curvature-like invariants. We show that these coefficients can be interpreted as the curvature of a canonical Ehresmann connection associated to the metric, first introduced in ...

On geometry of focal surfaces due to B-Darboux and type-2 Bishop frames in Euclidean 3-space

open access: yesAIMS Mathematics, 2022
In Euclidean 3-space $ {\mathrm{E}}^3 $, a canonical subject is the focal surface of such a cliched space curve, which would be a two-dimensional corrosive with Lagrangian discontinuities. The tubular surfaces with respect to the B-Darboux frame and type-

Non-commutative NLS-type hierarchies: dressing & solutions [PDF]

open access: yes, 2019
We consider the generalized matrix non-linear Schrodinger (NLS) hierarchy. By employing the universal Darboux-dressing scheme we derive solutions for the hierarchy of integrable PDEs via solutions of the matrix Gelfand-Levitan-Marchenko equation, and we ...

Equiaffine Darboux frames for codimension 2 submanifolds contained in hypersurfaces

open access: yesJournal of the Mathematical Society of Japan, 2017
Consider a codimension $1$ submanifold $N^n\subset M^{n+1}$, where $M^{n+1}\subset\mathbb{R}^{n+2}$ is a hypersurface. The envelope of tangent spaces of $M$ along $N$ generalizes the concept of tangent developable surface of a surface along a curve. In this paper, we study the singularities of these envelopes.

Smarandache Curves of the Evolute Curve According to Sabban Frame

open access: yesCommunications in Advanced Mathematical Sciences, 2020
The aim of this paper is to define Smarandache curves according to the Sabban frame belonging to the unit Darboux vector of spherical indicatrix curve of the evolute curve. Also, we calculate the geodesic curvatures of these curves.

$ C^* $-partner curves with modified adapted frame and their applications

open access: yesAIMS Mathematics, 2023
In this study, the curve theory, which occupies a very important and wide place in differential geometry, has been studied. One of the most important known methods used to analyze a curve in differential geometry is the Frenet frame, which is a moving ...

The Bianchi-Darboux transform of L-isothermic surfaces

open access: yes, 2000
We study an analogue of the classical Bianchi-Darboux transformation for L-isothermic surfaces in Laguerre geometry, the Bianchi-Darboux transformation.
