Extrinsic and intrinsic curvatures in thermodynamic geometry
Physics Letters B, 2016 We investigate the intrinsic and extrinsic curvatures of a certain hypersurface in thermodynamic geometry of a physical system and show that they contain useful thermodynamic information.

The geometric genus of hypersurface singularities [PDF]
, 2013 Using the path lattice cohomology we provide a conceptual topological characterization of the geometric genus for certain complex normal surface singularities with rational homology sphere links, which is uniformly valid for all superisolated and Newton ...

Bis[1]benzothieno[1,4]thiazine‐S‐oxides–Luminescence of the Anti‐Anti‐Regioisomer
Asian Journal of Organic Chemistry, EarlyView.Three regioisomeric bis[1]benzothieno[1,4]thiazine‐S‐oxides were synthesized by mild oxidation. Crystal structures reveal S‐extra‐oxide, N‐intra conformers with paired‐like substructures, and intermolecular distances as low as 3.30 Å. UV–vis absorption and emission spectroscopy identifies the anti‐anti‐regioisomer as a strong blue light emitter ...

Characterization of Biharmonic Hypersurface
Researches in Mathematics, 2022 The main purpose of this paper is to study biharmonic hypersurface in a quasi-paraSasakian manifold $\mathbb{Q}^{2m+1}$. Biharmonic hypersurfaces are special cases of biharmonic maps and biharmonic maps are the critical points of the bienergy functional.

Dimensional reduction to hypersurface of foliation [PDF]
, 2013 When the bulk spacetime has a foliation structure, the collective dynamics of the hypersurfaces should reveal certain aspects of the bulk physics. The procedure of reducing the bulk to a hypersurface, called ADM reduction, was implemented in [3] where ...

Angewandte Chemie International Edition, Accepted Article.Photoinitiated homolysis of element‐carbon bonds is an important method for the generation of carbon‐centered radicals in catalysis and organometallic or polymer chemistry. In this respect, the use of earth‐abundant main group elements such as aluminum or silicon is attractive.

Osculating hypersurfaces of higher order
Lietuvos Matematikos Rinkinys, 2011 Oscurating surfaces of second order have been studied in classical differential geometry [1]. In this article we generalize this notion to osculating hyper-surfaces of higher order of hyper-surfaces in Euclidean n-space.

Centro-affine hypersurface immersions with parallel cubic form [PDF]
, 2012 We consider non-degenerate centro-affine hypersurface immersions in $$\mathbb R^n$$Rn whose cubic form is parallel with respect to the Levi-Civita connection of the affine metric.

Communications on Pure and Applied Mathematics, EarlyView.Abstract Let (Mn,g)$(M^n,g)$ be a complete Riemannian manifold which is not isometric to Rn$\mathbb {R}^n$, has nonnegative Ricci curvature, Euclidean volume growth, and quadratic Riemann curvature decay. We prove that there exists a set G⊂(0,∞)$\mathcal {G}\subset (0,\infty)$ with density 1 at infinity such that for every V∈G$V\in \mathcal {G}$ there ...
