Warped product semi-slant submanifolds in locally conformal Kaehler manifolds

Pracì Mìžnarodnogo Geometričnogo Centru, 2017
In 1994, in [13], N. Papaghiuc introduced the notion of semi-slant submanifold in a Hermitian manifold which is a generalization of CR- and slant-submanifolds. In particular, he considered this submanifold in Kaehlerian manifolds, [13]. Then, in 2007, V.

Optimal Thermodynamic Processes For Gases

Entropy, 2020
In this paper, we consider an optimal control problem in the equilibrium thermodynamics of gases. The thermodynamic state of the gas is given by a Legendrian submanifold in a contact thermodynamic space.

An elementary approach to Wehrl‐type entropy bounds in quantitative form

Proceedings of the London Mathematical Society, Volume 133, Issue 1, July 2026.
Abstract We consider the problem of the stability (with sharp exponent) of the Lieb–Solovej inequality for symmetric SU(N)$SU(N)$ coherent states, which was obtained only recently by the authors. Here, we propose an elementary proof of this result, based on reformulating the Wehrl‐type entropy as a function defined on the unit sphere in Cd$\mathbb {C ...

ON THE GEOMETRY OF PARACOMPLEX SUBMANIFOLDS

Demonstratio Mathematica, 2001
The paracomplex submanifolds \(M\) in an almost parahermitian manifold (\(\overline M,\overline J,\overline g)\) with \(\overline J^2=I\), \(\overline g(X,\overline JY)+\overline g(\overline JX,Y)=0\) are characterized by \(\overline J(T_xM)=T_xM\) [see \textit{V. Cruceanu}, \textit{P. Fortuny} and \textit{P. M. Gradea} in Rocky Mt. J. Math. 26, 83-115

Optimal Inequalities Characterizing Totally Real Submanifolds in Quaternionic Space Form

Mathematics
In the present paper, we investigate some pinching inequalities on the scalar curvature of a totally real submanifold in quaternionic space form that leads to a topological conclusion of the submanifold. In addition, we construct another inequality which

First eigenvalue of submanifolds in Euclidean space

International Journal of Mathematics and Mathematical Sciences, 2000
We give some estimates of the first eigenvalue of the Laplacian for compact and non-compact submanifold immersed in the Euclidean space by using the square length of the second fundamental form of the submanifold merely.

The discriminant of quasi m-boundary singularities

Demonstratio Mathematica
We describe the discriminant of deformations of simple quasi m-boundary equivalence classes for m≥2m\ge 2. All quasi simple mm-boundary classes are right equivalent to Arnold’s singularities (ADE).

Biomechanical Modeling of Finger Joints Based on Dimeric Kinematics

Current Directions in Biomedical Engineering
In the literature, the proximal and distal interphalangeal joints (PIP and DIP) are usually described as singleaxis hinge joints, whereas the metacarpophalangeal (MCP) joint is typically described as a two-axis joint.
