The fundamental theorem of curves and classifications in the Heisenberg groups
• Mathematics
• 2015
We study the horizontally regular curves in the Heisenberg groups $H_n$. We show the fundamental theorem of curves in $H_n$ $(n\geq 2)$ and define the concept of the orders for horizontally regular
On Local Congruence of Immersions in Homogeneous or Nonhomogeneous Spaces
We show how to find a complete set of necessary and sufficient conditions that solve the fixed-parameter local congruence problem of immersions in G-spaces, whether ho- mogeneous or not, provided

Abstract New algorithms for determining discrete and continuous symmetries of polynomials - also known as binary forms in classical invariant theory - are presented, and implemented in MAPLE. The
Differential invariants for parametrized projective surfaces
• Mathematics
• 1999
The differential invariants associated with a transformation group acting on a manifold are the fundamental building blocks for understanding the geometry, equivalence, symmetry and other properties
The $\kappa$-nullity of Riemannian manifolds and their splitting tensors

. We consider Riemannian n -manifolds M with nontrivial κ -nullity “distribution” of the curvature tensor R , namely, the variable rank distribu- tion of tangent subspaces to M where R coincides with

The proposed approach is based on the Frenet frame utilized in differential geometry and provides a general framework for the definition of the time derivative of electrical quantities in stationary as well as transient conditions.
Conformal geometry of isotropic curves in the complex quadric
• Mathematics
International Journal of Mathematics
• 2022
Let Q3 be the complex 3-quadric endowed with its standard complex conformal structure. We study the complex conformal geometry of isotropic curves in Q3. By an isotropic curve we mean a nonconstant
