Special Issue Information

Dear Colleagues,

As an important branch of mathematics, differential geometry provides a mathematical framework for understanding the geometric structures and properties of spaces. Differential geometry encompasses a wide range of topics and has applications in various areas of mathematics, physics, engineering, and computer graphics, among others. This Special Issue, as a follow-up of the previous edition, is devoted to novel research on differential geometry, geometric analysis, and their wide-ranging applications. The topics covered in this Special Issue include, but are not limited to, the following:

  1. Differential Geometry: Riemannian geometry, manifolds, Finsler geometry, symplectic geometry, contact geometry, complex and Kähler geometry, geodesic mappings, Minkowski spaces, almost geodesic mappings, etc.
  2. Geometric Analysis: minimal surfaces, geometric flows, geometric measure theory, geometric functional theory, geometric inequalities, such as the isoperimetric inequality, Sobolev inequalities, and the Minkowski inequality.
  3. Geometric Methods in Image Processing and Computer Vision: topics such as geometric transformations, shape analysis, geometric modeling, and geometric methods for image registration and segmentation.
  4. Applications in Engineering and Applied Sciences.

All the related topics on the areas of differential geometry and geometric analysis are of interest for this Special Issue.

This paper extends the theory of Riemannian maps to the setting of generic submanifolds of Kähler manifolds. We introduce the notion of holomorphic Riemannian maps from generic submanifolds and establish fundamental relations between the geometric structures involved. Our main results include a characterization of when the image distribution inherits a Kähler structure, a harmonicity criterion for such maps, and a relation between holomorphic sectional curvatures. The theory developed here generalizes previous work on CR-submanifolds while demonstrating new phenomena specific to the generic case. Several explicit examples illustrate the non-trivial nature of our results. Full article

This paper studies the conformal geometry of complete gradient Schouten solitons (GSSs) admitting closed conformal vector fields (CVFs). We establish rigidity and characterization results for nonparallel, homothetic closed CVFs under the assumption that the gradient of the scalar curvature is parallel to the CVF. It is shown that such manifolds are isometric to Euclidean space. Moreover, complete noncompact GSSs with constant scalar curvature are locally conformally flat in dimension four and have harmonic Weyl curvature in higher dimensions. Finally, we prove that these manifolds are totally umbilical if and only if their scalar curvature is constant, and they form warped products with space forms. Full article

This study explores parallel hypersurfaces in four-dimensional Euclidean space E4, deriving explicit expressions for their Gaussian and mean curvatures in terms of the curvature functions of the base hypersurface. We identify conditions under which these parallel hypersurfaces are flat or minimal. The theory is applied to several key hypersurfaces, including rotational hypersurfaces, hyperspheres, catenoidal hypersurfaces, and helicoidal hypersurfaces, with detailed curvature computations and visualizations. These results not only extend classical curvature relations into higher-dimensional spaces but also offer valuable insights into curvature transformations, with practical applications in both theoretical and computational geometry.

In this paper, we investigate hypersurfaces in the nearly Kähler 6-sphere S6 and establish several foundational results. In particular, under certain conditions of the function ξ(f)=g(f,ξ), we demonstrate that a hypersurface M of S6 must be a sphere. Here, fC(M) is a smooth vector field, ξ=JN denotes the characteristic vector field, J is the almost complex structure on S6, and N is the unit vector field normal to the hypersurface. We also support our results with illustrative examples. Full article
