Benenti Tensors: A useful tool in Projective Differential Geometry [PDF]

open access: yesComplex Manifolds, 2018
Two metrics are said to be projectively equivalent if they share the same geodesics (viewed as unparametrized curves). The degree of mobility of a metric g is the dimension of the space of the metrics projectively equivalent to g. For any pair of metrics

Walls and asymptotics for Bridgeland stability conditions on 3-folds [PDF]

open access: yesÉpijournal de Géométrie Algébrique, 2022
We consider Bridgeland stability conditions for three-folds conjectured by Bayer-Macr\`i-Toda in the case of Picard rank one. We study the differential geometry of numerical walls, characterizing when they are bounded, discussing possible intersections ...

Terracini Loci: Dimension and Description of Its Components

open access: yesMathematics, 2023
We study the Terracini loci of an irreducible variety X embedded in a projective space: non-emptiness, dimensions and the geometry of their maximal dimension’s irreducible components.

FORMATION OF MODERN MATHEMATICAL APPROACH TO SOLVING PROBLEMS OF PHYSICS

open access: yesФізико-математична освіта, 2022
Formulation of the problem. Precision studies of the Higgs boson, supersymmetric particles, the magnetic moment of the muon, electric dipole moment of the electron, flavor anomalies demonstrate the deviation beyond Standard Model. They are connected with

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

open access: yesDiscrete 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.

Centered planes in the projective connection space

open access: yesДифференциальная 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 ...

Projective differential geometry of curved surfaces. II [PDF]

open access: yesTransactions of the American Mathematical Society, 1907
The theory of surfaces, as developed by the author in the preceding three memoirs, was based upon the assumption that the surface considered was referred to its asymptotic curves. The complete system of invariants and covariallts was set up on that hypothesis.

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

open access: yesLietuvos 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 ...
