Some Characterizations of the Cobb-Douglas and CES Production Functions in Microeconomics
Abstract and Applied Analysis, 2013 It is well known that the study of the shape and the properties of the production possibility frontier is a subject of great interest in economic analysis.

Ligand Field Tuning of Photoreactivity: Contrasting Low‐Spin and High‐Spin Fe(III)‐Azido Complexes
ChemPhotoChem, Volume 10, Issue 1, January 2026.Why do near‐identical Fe(III)‐azido complexes exhibit different photoreactivity profiles? Linking spin states and key normal modes to wavelength‐dependent photoreductive and photooxidative reaction paths shows how supposedly minor structural changes influence the spin ground state, in turn dictating the photoreactivity profile of the complexes.

, 2019 A well-known conjecture of Yau states that the area of one of Clifford minimal hypersurfaces $S^k\big{(}\sqrt{\frac{k}{n}}\, \big{)}\times S^{n-k}\big{(}\sqrt{\frac{n-k}{n}}\, \big{)}$ gives the lowest value of area among all non-totally geodesic compact minimal hypersurfaces in the unit sphere $S^{n+1}(1)$.

Families of singular algebraic varieties that are rationally elliptic spaces
Mathematische Nachrichten, Volume 299, Issue 1, Page 214-223, January 2026.Abstract We discuss families of hypersurfaces with isolated singularities in projective space with the property that the sum of the ranks of the rational homotopy and the homology groups is finite. They represent infinitely many distinct homotopy types with all hypersurfaces having a nef canonical or anti‐canonical class.

Weak Minimal Area in Entanglement Entropy
Advances in High Energy Physics, 2015 We revisit the minimal area condition of Ryu-Takayanagi in the holographic calculation of the entanglement entropy, in particular, the Legendre test and the Jacobi test. The necessary condition for the weak minimality is checked via Legendre test and its

FTheoryTools: Advancing Computational Capabilities for F‐Theory Research
Fortschritte der Physik, Volume 74, Issue 1, January 2026.Abstract A primary goal of string phenomenology is to identify realistic four‐dimensional physics within the landscape of string theory solutions. In F‐theory, such solutions are encoded in the geometry of singular elliptic fibrations, whose study often requires particularly challenging and cumbersome computations.

On higher Jacobians, Laplace equations, and Lefschetz properties
Bulletin of the London Mathematical Society, Volume 58, Issue 1, January 2026.Abstract Let A$A$ be a standard graded Artinian K$\mathbb {K}$‐algebra over a field of characteristic zero. We prove that the failure of strong Lefschetz property (SLP) for A$A$ is equivalent to the osculating defect of a certain rational variety.

A complete minimal hypersurface in de Sitter space-time of the first kind
Дифференциальная геометрия многообразий фигур, 2018 In the present paper we prove that a complete spacelike minimal hypersurface in de Sitter space-time of the first kind is a spherical space form if it has an integrable p-power of its scalar curvature for some positive p.

Plank theorems and their applications: A survey
Bulletin of the London Mathematical Society, Volume 58, Issue 1, January 2026.Abstract Plank problems concern the covering of convex bodies by planks in Euclidean space and are related to famous open problems in convex geometry. In this survey, we introduce plank problems and present surprising applications of plank theorems in various areas of mathematics.
