Geometric Mechanics on Warped Product Semi-Slant Submanifold of Generalized Complex Space Forms
Advances in Mathematical Physics, 2021 In this study, we develop a general inequality for warped product semi-slant submanifolds of type Mn=NTn1×fNϑn2 in a nearly Kaehler manifold and generalized complex space forms using the Gauss equation instead of the Codazzi equation.

WIREs Computational Statistics, Volume 15, Issue 5, September/October 2023., 2023 The graph illustrates brain changes in regional metabolic activity and connectivity in a cohort of mildly cognitively impaired patients. The depicted changes reflect patterns at 24 months relative to baseline and are determined by Bayesian Spatial Modeling of activation and connectivity (BSMac).

Nonnegative scalar curvature on manifolds with at least two ends
Journal of Topology, Volume 16, Issue 3, Page 855-876, September 2023., 2023 Abstract Let M$M$ be an orientable connected n$n$‐dimensional manifold with n∈{6,7}$n\in \lbrace 6,7\rbrace$ and let Y⊂M$Y\subset M$ be a two‐sided closed connected incompressible hypersurface that does not admit a metric of positive scalar curvature (abbreviated by psc). Moreover, suppose that the universal covers of M$M$ and Y$Y$ are either both spin

Journal of Mathematics, Volume 2023, Issue 1, 2023., 2023 This paper focuses on the investigation of semi‐invariant warped product submanifolds of Sasakian space forms endowed with a semisymmetric metric connection. We delve into the study of these submanifolds and derive several fundamental results. Additionally, we explore the practical implications of our findings by applying them to the homology analysis ...

Pointwise Hemislant Submanifolds in a Complex Space Form
Journal of Mathematics, Volume 2023, Issue 1, 2023., 2023 In this paper, pointwise hemislant submanifolds were introduced in a Kahler manifold. The integrability conditions for the distributions which are involved in the definition of a pointwise hemislant submanifold were investigated. In addition, the necessary and sufficient conditions were given for a pointwise hemislant submanifold to be a pointwise ...

Review of the techniques used in motor‐cognitive human‐robot skill transfer
Cognitive Computation and Systems, Volume 3, Issue 3, Page 229-252, September 2021., 2021 Abstract A conventional robot programming method extensively limits the reusability of skills in the developmental aspect. Engineers programme a robot in a targeted manner for the realisation of predefined skills. The low reusability of general‐purpose robot skills is mainly reflected in inability in novel and complex scenarios.

Examples of noncompact nonpositively curved manifolds
Bulletin of the London Mathematical Society, Volume 53, Issue 4, Page 1061-1071, August 2021., 2021 Abstract We give a simple construction of new, complete, finite volume manifolds M of bounded, nonpositive curvature. These manifolds have ends that look like a mixture of locally symmetric ends of different ranks and their fundamental groups are not duality groups.

Mathematical Problems in Engineering, Volume 2021, Issue 1, 2021., 2021 Recently, we have obtained Ricci curvature inequalities for skew CR‐warped product submanifolds in the framework of complex space form. By the application of Bochner’s formula on these inequalities, we show that, under certain conditions, the base of these submanifolds is isometric to the Euclidean space.

A Study of Doubly Warped Product Immersions in a Nearly Trans‐Sasakian Manifold with Slant Factor
Advances in Mathematical Physics, Volume 2021, Issue 1, 2021., 2021 In this article, we discuss the de Rham cohomology class for bislant submanifolds in nearly trans‐Sasakian manifolds. Moreover, we give a classification of warped product bislant submanifolds in nearly trans‐Sasakian manifolds with some nontrivial examples in the support.
