Torsion and the second fundamental form for distributions

open access: yes, 2015
The second fundamental form of Riemannian geometry is generalised to the case of a manifold with a linear connection and an integrable distribution. This bilinear form is generally not symmetric and its skew part is the torsion.

Efficient Classification of Motor Imagery Electroencephalography Signals Using Deep Learning Methods

open access: yesSensors, 2019
Single-trial motor imagery classification is a crucial aspect of brain–computer applications. Therefore, it is necessary to extract and discriminate signal features involving motor imagery movements.

Integrable Equations and Their Evolutions Based on Intrinsic Geometry of Riemann Spaces

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2009
The intrinsic geometry of surfaces and Riemannian spaces will be investigated. It is shown that many nonlinear partial differential equations with physical applications and soliton solutions can be determined from the components of the relevant metric ...
