On the Kaehler rank of compact complex surfaces [PDF]

open access: yesBulletin de la Société mathématique de France, 2008
Harvey and Lawson introduced the Kaehler rank and computed it in connection to the cone of positive exact currents of bidimension (1,1) for many classes of compact complex surfaces.

Holomorphic flexibility properties of compact complex surfaces [PDF]

open access: yesInternational Mathematics Research Notices, 2013
We introduce the notion of a stratified Oka manifold and prove that such a manifold $X$ is strongly dominable in the sense that for every $x\in X$, there is a holomorphic map $f:\C^n\to X$, $n=\dim X$, such that $f(0)=x$ and $f$ is a local biholomorphism

Indefinite Kähler-Einstein Metrics on Compact Complex Surfaces [PDF]

open access: yesCommunications in Mathematical Physics, 1997
Indefinite Kaehler solutions of the Einstein equations are studied, and it is almost completely determined which compact complex surfaces admit such metrics.

Conformal duality and compact complex surfaces

open access: yesMathematische Annalen, 1986
Let M be a compact complex surface with first Betti number \(b_ 1\) which admits a compatible anti-self-dual metric g. In this paper we prove that if \(b_ 1\) is even, then g is conformally equivalent to a Kähler metric with zero scalar curvature and if \(b_ 1\) is odd then g is conformally equivalent to a locally conformally Kähler metric with ...

Geometric structures on compact complex analytic surfaces

open access: yesTopology, 1986
Starting from the recent determination of the Thurston geometries in dimension 4, this paper makes a study of manifolds with the various geometric structures. In preliminary sections, the list is recalled. There are 19 types of geometry (one of which is an infinite family), in 14 of which there is a complex structure (Kähler in 9 of the cases ...

Automorphism Groups of Compact Complex Surfaces [PDF]

open access: yesInternational Mathematics Research Notices, 2019
Abstract We study automorphism groups and birational automorphism groups of compact complex surfaces. We show that the automorphism group of such a surface $X$ is always Jordan, and the birational automorphism group is Jordan unless $X$ is birational to a product of an elliptic and a rational curve.

Improved Viability of Probiotics via Microencapsulation in Whey-Protein-Isolate-Octenyl-Succinic-Anhydride-Starch-Complex Coacervates

open access: yesMolecules, 2023
The aim of this study was to microencapsulate probiotic bacteria (Lactobacillus acidophilus 11073) using whey-protein-isolate (WPI)–octenyl-succinic-anhydride-starch (OSA-starch)-complex coacervates and to investigate the effects on probiotic bacterial ...
