Geometry of warped product pointwise semi-slant submanifolds of locally product Riemannian manifolds

Journal of Geometry and Physics, 2020
The authors introduce the notion of pointwise semi-slant submanifolds of locally product Riemannian manifolds as a generalization of pointwise slant submanifolds of almost Hermitian manifolds defined by \textit{B.-Y. Chen} and \textit{O. J. Garay} [Turk. J. Math. 36, No.

Acoustic source localization in ocean waveguides using principles of Riemannian geometry

Journal of the Acoustical Society of America, 2016
Source localization in underwater acoustics entails a comparison between acoustic fields involving some measure of correlation, looking for similarity between the acoustic field propagated from the true source location and replica fields propagated from different locations in the waveguide.

Local Riemannian Geometry of Foliations

1998
For two arbitrary complementary orthogonal distributions T1 and T2 on TM, we define the structural tensors B1 : T2 × T1 → T1 and B2 : T1 × T2 → T2 by the following formulas: $$ B_1 \left( {y,x} \right) = P_1 \left( {\nabla _x y} \right),{\text{ }}B_2 \left( {x,y} \right) = P_2 \left( {\nabla _y x} \right), $$ (2.1) were P i : TM → T i (i = 1,

Note on localized solutions of a nonlinear Klein-Gordon equation related to Riemannian geometry

Physical Review D, 1978
A nonlinear complex scalar field with a phi/sup 2d//(d - 2) self-interaction is considered in a flat, (d + 1) -dimensional space-time. Conformal techniques familiar in differential geometry become operative in the construction of exact, ''soliton''-type solutions exhibiting finite energies, but exponential decays.

Graded Riemannian geometry and graded fibre bundles, a context for local super-gauge theories

2005
Starting from Kostant's definition of a graded manifold [1], we present graded versions of tensor algebra, Riemannian metrics, Lie groups and actions (these are also defined by Kostant but we present a directly geometrical definition which is more convenient for our purposes), vector bundles, and principal bundles.

Geometry of Warped Product Semi-Invariant Submanifolds of a Locally Riemannian Product Manifold

2016
In this article, we have studied warped product semi-invariant submanifolds in a locally Riemannian product manifold and introduced the notions of a warped product semi-invariant submanifold. We have also proved several fundamental properties of a warped product semi-invariant in a locally Riemannian product manifold.
