A Generalization of the Goldberg-Sachs Theorem and its Consequences
, 2013 The Goldberg-Sachs theorem is generalized for all four-dimensional manifolds endowed with torsion-free connection compatible with the metric, the treatment includes all signatures as well as complex manifolds.

Chemokines and Their Association With Symptom Severity in Women With Endometriosis
American Journal of Reproductive Immunology, Volume 94, Issue 3, September 2025.ABSTRACT Problem Various chemokines have been linked to endometriosis. Notably, chemokines such as CCL2, CXCL8, and CXCL1 have also been shown to promote nociception. In this study, we investigated whether increased serum concentrations and endometrial expression of chemokines (specifically CCL2, CXCL8, and CXCL1) are associated with heightened ...

Twisted holomorphic symplectic forms
, 2015 We show that a compact Kahler manifold admitting a nondegenerate holomorphic 2-form valued in a line bundle is a finite cyclic cover of a hyperkahler manifold. With respect to the connection induced by the locally hyperkahler metric, the form is parallel.

Conservation Science and Practice, Volume 7, Issue 9, September 2025.The topics present among statements of the intended outcome of threat mapping research. Abstract There are often mismatches between the needs of decision makers and the outputs of scientific research, limiting the potential for conservation actions to be evidence‐based.

Reduction of Generalized Complex Structures
, 2008 We study reduction of generalized complex structures. More precisely, we investigate the following question. Let $J$ be a generalized complex structure on a manifold $M$, which admits an action of a Lie group $G$ preserving $J$. Assume that $M_0$ is a $G$

Exponential actions defined by vector configurations, Gale duality, and moment‐angle manifolds
Bulletin of the London Mathematical Society, Volume 57, Issue 9, Page 2571-2629, September 2025.Abstract Exponential actions defined by vector configurations provide a universal framework for several constructions of holomorphic dynamics, non‐Kähler complex geometry, toric geometry and topology. These include leaf spaces of holomorphic foliations, intersections of real and Hermitian quadrics, the quotient construction of simplicial toric ...

The Algebraic Index Theorem and Fedosov Quantization of Lagrange-Finsler and Einstein Spaces
, 2013 Various types of Lagrange and Finsler geometries and the Einstein gravity theory, and modifications, can be modelled by nonholonomic distributions on tangent bundles/ manifolds when the fundamental geometric objects are adapted to nonlinear connection ...

Taking limits in topological recursion
Journal of the London Mathematical Society, Volume 112, Issue 3, September 2025.Abstract When does topological recursion applied to a family of spectral curves commute with taking limits? This problem is subtle, especially when the ramification structure of the spectral curve changes at the limit point. We provide sufficient (straightforward‐to‐use) conditions for checking when the commutation with limits holds, thereby closing a ...
