Journal of Inequalities and Applications, 2018 Given a null hypersurface of a Lorentzian manifold, we isometrically immerse a null hypersurface equipped with the Riemannian metric (induced on it by the rigging) into a Riemannian manifold suitably constructed on the Lorentzian manifold.

Analytic Detection in Homotopy Groups of Smooth Manifolds
Современная математика: Фундаментальные направления, 2020 In this paper, for the mapping of a sphere into a compact orientable manifoldSn→M,n⩾1, we solve the problem of determining whether it represents a nontrivial element in the homotopy group of the manifoldπn(M) πn(M ). For this purpose, we consistently use

Advances in Mathematics, 2023 Q-Gorenstein toric contact manifolds provide an interesting class of examples of contact manifolds with torsion first Chern class. They are completely determined by certain rational convex polytopes, called toric diagrams, and arise both as links of toric isolated singularities and as prequantizations of monotone toric symplectic orbifolds.

IMPROVED CHEN’S INEQUALITIES FOR LAGRANGIAN SUBMANIFOLDS IN QUATERNIONIC SPACE FORMS [PDF]
Romanian Journal of Mathematics and Computer Science, 2016 Riemannian invariants (in particular Chen invariants) play an important role in the theory of submanifolds. They are very useful in providing relationships between the extrinsic and intrinsic invariants of a submanifold.

Topological invariants for gauge theories and symmetry-protected topological phases
, 2015 We study the braiding statistics of particle-like and loop-like excitations in 2D and 3D gauge theories with finite, Abelian gauge group. The gauge theories that we consider are obtained by gauging the symmetry of gapped, short-range entangled, lattice ...

Inequalities involving k-Chen invariants for submanifolds of Riemannian product manifolds
Communications Faculty Of Science University of Ankara Series A1Mathematics and Statistics, 2018 Summary: An optimal inequality involving the scalar curvatures, the mean curvature and the \(k\)-Chen invariant is established for Riemannian submanifolds. Particular cases of this inequality is reported. Furthermore, this inequality is investigated on submanifolds, namely slant, \(F\)-invariant and \(F\)-anti invariant submanifolds of an almost ...

Advances in Difference Equations, 2018 The construction of implicit Runge–Kutta–Nyström (RKN) method is considered in this paper. Based on the symmetric, symplectic, and exponentially fitted conditions, a class of implicit RKN integrators is obtained.

Chen-Type Inequality for Generic Submanifolds of Quaternionic Space Form and Its Application
Journal of New TheoryIn 1993, the theory of Chen invariants started when Chen wrote basic inequalities for submanifolds in space forms. This inequality is called Chen’s first inequality. Afterward, many geometers studied many papers dealing with this new inequality.

A Mirror Theorem for Toric Stacks
, 2014 We prove a Givental-style mirror theorem for toric Deligne--Mumford stacks X. This determines the genus-zero Gromov--Witten invariants of X in terms of an explicit hypergeometric function, called the I-function, that takes values in the Chen--Ruan ...
