Chern Flat and Chern Ricci-Flat Twisted Product Hermitian Manifolds
MathematicsLet (M1,g) and (M2,h) be two Hermitian manifolds. The twisted product Hermitian manifold (M1×M2f,G) is the product manifold M1×M2 endowed with the Hermitian metric G=g+f2h, where f is a positive smooth function on M1×M2.

Some applications of canonical metrics to Landau–Ginzburg models
Journal of the London Mathematical Society, Volume 111, Issue 4, April 2025.Abstract It is known that a given smooth del Pezzo surface or Fano threefold X$X$ admits a choice of log Calabi–Yau compactified mirror toric Landau–Ginzburg model (with respect to certain fixed Kähler classes and Gorenstein toric degenerations).

Multiscale Differential Geometry Learning for Protein Flexibility Analysis
Journal of Computational Chemistry, Volume 46, Issue 7, March 15, 2025.Protein structure fluctuations, as measured by B‐factors, are closely linked to protein flexibility and function. Predicting B‐factors is an important research topic that has led to the development of various predictive models. Atomic interactions within proteins can be described using a family of low‐dimensional manifolds.

Pseudohermitian geometry on contact Riemannian manifolds [PDF]
Rendiconti di Matematica e delle Sue Applicazioni, 2002 Starting from work by S. Tanno, [39], and E. Barletta et al., [3], we study the geometry of (possibly non integrable) almost CR structures on contact Riemannian manifolds.

Matter field Kähler metric in heterotic string theory from localisation
Journal of High Energy Physics, 2018 We propose an analytic method to calculate the matter field Kähler metric in heterotic compactifications on smooth Calabi-Yau three-folds with Abelian internal gauge fields.

The BIonic diode in a system of trigonal manifolds [PDF]
arXiv, 2017 A BIonic diode is constructed of two polygonal manifolds connected by a Chern-Simons manifold. The shape and the angle between atoms of molecules on the boundary of two polygonal manifolds are completely different. For this reason, electrons on the Chern-Simons manifold are repelled by molecules at the boundary of one manifold and absorbed by molecules

AI Magazine, Volume 46, Issue 1, Spring 2025.Abstract A cornerstone of machine learning is the identification and exploitation of structure in high‐dimensional data. While classical approaches assume that data lies in a high‐dimensional Euclidean space, geometric machine learning methods are designed for non‐Euclidean data, including graphs, strings, and matrices, or data characterized by ...

Mass-deformed M2 branes in Stenzel space
Journal of High Energy Physics, 2017 We obtain finite-temperature M2 black branes in 11-dimensional supergravity, in a G 4-flux background whose self-dual part approaches a solution of Cvetič, Gibbons, Lü, and Pope, based upon Stenzel’s family of Ricci-flat Kähler deformed cones.

Rational homotopy types of mirror manifolds [PDF]
arXiv, 1999 We explain how to relate the problem of finding a mirror manifold for a Calabi-Yau manifold to the problem of characterizing the rational homotopy types of closed K\"{a}hler manifolds.

Where Does the Time Go? Auditors’ Commercial Effort, Professional Effort, and Audit Quality
Journal of Accounting Research, Volume 63, Issue 1, Page 255-317, March 2025.ABSTRACT Audit theory and regulation assumes that auditors’ commercial motivation threatens audit quality. In this registered report, we use data from two Big Four firms in the Netherlands and provide empirical evidence on the relation between auditors’ commercial motivation and (1) compensation, (2) total audit effort, and (3) audit quality.
