Centered planes in the projective connection space

Дифференциальная геометрия многообразий фигур, 2020
The space of centered planes is considered in the Cartan projec­ti­ve connection space . The space is important because it has con­nec­tion with the Grassmann manifold, which plays an important role in geometry and topology, since it is the basic space ...

On conjugate difference schemes: the midpoint scheme and the trapezoidal scheme

Discrete and Continuous Models and Applied Computational Science, 2021
The preservation of quadratic integrals on approximate solutions of autonomous systems of ordinary differential equations x=f(x), found by the trapezoidal scheme, is investigated.

Shape Synchronization in Driver-Response of 4-D Chaotic System and Its Application in Image Encryption

IEEE Access, 2020
In this paper, we put forward on the drive-response synchronization in shape for four-dimensional (4-D) continuous chaotic system, using the basic theory of plane curves in classical differential geometry. For 4-D continuous system, shape synchronization

Geometry of nonholonomic complexes NGr (1, 5, 5)

Lietuvos Matematikos Rinkinys, 2011
In this article the differential geometry of nonholonomic complexes in five dimensional projective space is considered. The algebraic structure of the first fundamental object is considered and the geometrcal interpretations of some comitants of the ...

Positive geometries and differential forms with non-logarithmic singularities. Part I

Journal of High Energy Physics, 2020
Positive geometries encode the physics of scattering amplitudes in flat space- time and the wavefunction of the universe in cosmology for a large class of models.

Integrable systems in projective differential geometry [PDF]

, 1999
Some of the most important classes of surfaces in projective 3-space are reviewed: these are isothermally asymptotic surfaces, projectively applicable surfaces, surfaces of Jonas, projectively minimal surfaces, etc.

Differential Geometry of Submanifolds of Projective Space [PDF]

, 2008
These are lecture notes on the rigidity of submanifolds of projective space "resembling" compact Hermitian symmetric spaces in their homogeneous embeddings. Recent results are surveyed, along with their classical predecessors. The notes include an introduction to moving frames in projective geometry, an exposition of the Hwang-Yamaguchi ridgidity ...
