Local Rigidity of Submanifolds

2019
One of the basic problems in submanifold theory addressed in this book concerns the uniqueness of isometric immersions \(f\colon M^n\to \mathbb {Q}_c^m\) of Riemannian manifolds into space forms. Clearly, since g = τ ∘ f is also an isometric immersion for any isometry \(\tau \colon \mathbb {Q}_c^m\to \mathbb {Q}_c^m\), uniqueness should be understood ...

LOCAL KNOTTING OF SUBMANIFOLDS

Mathematics of the USSR-Sbornik, 1973
In this paper the author investigates the modification of the fundamental group of the complement of a submanifold of codimension 2 by knotting in a neighborhood of one of its points. With the aid of such knotting he constructs closed nonorientable surfaces in R4 with finite noncommutative groups.

Fusion of submanifold and local texture features for palmprint authentication

2015 Visual Communications and Image Processing (VCIP), 2015
In this paper, a palmprint based authentication system is proposed. The proposed system makes use of locality sensitive discriminant analysis and directional local extrema patterns. A locality sensitive discriminant analysis has the capability to project the palmprints into a new space, where the palmprints belonging to same class become closer ...

On submanifolds of locally product Riemannian manifolds

TRU Mathematics, 1982
Inspired by the properties of CR-submanifolds of a Kählerian manifold [\textit{A. Bejancu}, Proc. Am. Math. Soc. 69, 135-142 (1978; Zbl 0368.53040); Trans. Am. Math. Soc. 250, 333-345 (1979; Zbl 0368.53041)], the author studies submanifolds of almost product Riemannian manifolds.
