Surfaces kählériennes de volume fini et équations de Seiberg-Witten

Yann Rollin (2002)

Bulletin de la Société Mathématique de France

Soit $M = ℙ (ℰ)$ une surface complexe réglée. Nous introduisons des métriques de volume fini sur $M$ dons les singularités sont paramétrisées par une structure parabolique sur le fibré $ℰ$ . Nous généralisons alors un résultat de Burns-deBartolomeis et Le Brun, en montrant que l’existence de métriques kählériennes singulières, de volume fini, à courbure scalaire constante négative ou nulle sur $M$ est équivalente à une condition de polystabilité parabolique sur $ℰ$ ; de plus ces métriques proviennent toutes de quotients...

Surfaces with parallel second fundamental form in Bianchi-Cartan-Vranceanu spaces

Mohamed Belkhelfa, Franki Dillen, Jun-ichi Inoguchi (2002)

We give a complete classification of surfaces with parallel second fundamental form in 3-dimensional Bianchi-Cartan-Vranceanu spaces.

Surfaces with prescribed Weingarten operator

Udo Simon, Konrad Voss, Luc Vrancken, Martin Wiehe (2002)

Banach Center Publications

We investigate pairs of surfaces in Euclidean 3-space with the same Weingarten operator in case that one surface is given as surface of revolution. Our local and global results complement global results on ovaloids of revolution from S-V-W-W.

Symmetries and Kähler-Einstein metrics

Claudio Arezzo, Alessandro Ghigi (2005)

Bollettino dell'Unione Matematica Italiana

We consider Fano manifolds $M$ that admit a collection of finite automorphism groups $G_{1}, ..., G_{k}$ , such that the quotients $M / G_{i}$ are smooth Fano manifolds possessing a Kähler-Einstein metric. Under some numerical and smoothness assumptions on the ramification divisors, we prove that $M$ admits a Kähler-Einstein metric too.
