On Non‐Compact Extended Bach Solitons

Mathematische Nachrichten, Volume 299, Issue 5, Page 1140-1151, May 2026.
ABSTRACT We study the characterization of non‐compact solitons of the extended Bach flow, known as an extended Bach soliton. We prove that a weakly conformally flat extended Bach soliton (Mn,g,V)$(M^n,g,V)$ with harmonic Weyl tensor is Bach‐flat and the potential vector field V$V$ is conformal.

Chen inequalities on warped product Legendrian submanifolds in Kenmotsu space forms and applications

Journal of Inequalities and Applications
In the current work, we study the geometry and topology of warped product Legendrian submanifolds in Kenmotsu space forms F 2 n + 1 ( ϵ ) $\mathbb{F}^{2n+1}(\epsilon )$ and derive the first Chen inequality, including extrinsic invariants such as the mean

Curvature Invariants on Partially Totally Real Submanifolds in Complex Space Forms

Mathematics
Kähler manifolds are the most studied complex manifolds. A Kähler manifold with constant holomorphic sectional curvature is said to be a complex space form. There are special classes of submanifolds in Kähler manifolds. Recently, Poyraz et al.

Hitchhiker's Guide to the Swampland: The Cosmologist's Handbook to the String‐Theoretical Swampland Programme

Fortschritte der Physik, Volume 74, Issue 4, April 2026.
Abstract String theory has strong implications for cosmology, implying the absence of a cosmological constant, ruling out single‐field slow‐roll inflation, and that black holes decay. The origins of these statements are elucidated within the string‐theoretical swampland programme.

Witten genera of complete intersections

Bulletin of the London Mathematical Society, Volume 58, Issue 2, February 2026.
Abstract We prove vanishing results for Witten genera of string generalized complete intersections in homogeneous Spinc$\text{Spin}^c$‐manifolds and in other Spinc$\text{Spin}^c$‐manifolds with Lie group actions. By applying these results to Fano manifolds with second Betti number equal to one we get new evidence for a conjecture of Stolz.

Multinational Enterprises' ESG Strategy Against Institutional Pressures in Emerging Markets: The Moderating Effect of Digitalization Capability

Business Strategy and the Environment, Volume 34, Issue 8, Page 10373-10394, December 2025.
ABSTRACT This study examined the institutional pressures that influence the implementation of a multinational enterprises' (MNEs) environmental, social, and governance (ESG) strategy in emerging markets. It investigated the sustainable performance (i.e., financial, social, and environmental performance) resulting from MNEs' strategic responses to ...

Ricci curvature of real hypersurfaces in complex hyperbolic space [PDF]

, 2002
summary:First we prove a general algebraic lemma. By applying the algebraic lemma we establish a general inequality involving the Ricci curvature of an arbitrary real hypersurface in a complex hyperbolic space.
