Mihai Paun, Positivity of quotients of holomorphic tensor fields (Lecture I)
Mihai Paun, Positivity of quotients of holomorphic tensor fields (Lecture I)
Speaker Mihai Paun U. Bayreuth I will present the main results and techniques in the preprint arxiv:2502.02183 (joint with J. Cao). This was motivated by the recent preprint by W. Ou, cf. arXiv:2501.1808 (especially by the algebraicity criteria for foliations on compact Kähler manifolds in this article). The first lecture is dedicated to …

Thibaut Delcroix, Weighted Kähler geometry and semisimple principal fibrations (Lecture I)
Thibaut Delcroix, Weighted Kähler geometry and semisimple principal fibrations (Lecture I)
Speaker Thibaut Delcroix Université de Montpellier In Kähler geometry, especially in the questions of existence of canonical Kähler metrics, the volume form ωn associated with a Kähler form ω plays a central role. In weighted Kähler geometry, we consider a Kähler manifold X equipped with a Hamiltonian action of a torus T, a …

Mihai Paun, Hermitian-Einstein metrics for stable coherent sheaves and Bogomolov-Gieseker inequality(Lecture III)
Mihai Paun, Hermitian-Einstein metrics for stable coherent sheaves and Bogomolov-Gieseker inequality(Lecture III)
Speaker Mihai Paun U. Bayreuth I will survey the main results obtained in the articles arXiv:2501.18088 and arXiv:2405.10003. There will be no "serious" proofs, I will nevertheless try to highlight the main ingredients in our arguments.

Jinhyung Park, Effective gonality theorem on weight-one syzygies of algebraic curves
Jinhyung Park, Effective gonality theorem on weight-one syzygies of algebraic curves
Speaker Jinhyung Park KAIST In 1986, Green-Lazarsfeld raised the gonality conjecture asserting that the gonality gon(C) of a smooth projective curve C of genus g can be read off from weight-one syzygies of a sufficiently positive line bundle L, and also proposed possible least degree of L, that is 2g+gon(C)-1. In 2015, Ein-Lazarsfeld …

Long Li, Plurisubharmonic functions and Sasaki geometry
Long Li, Plurisubharmonic functions and Sasaki geometry
Speaker Long Li ShanghaiTech University In this talk, we will discuss the recent progress on the zero mass conjecture for plurisubharmoinc functions, raised by Guedj and Rashkovskii. For a local plurisubharmonic function with an isolated singularity at the origin, the conjecture states that the zero Lelong number (at the singularity) implies the zero …

Jie Liu, Symplectic singularities arising from contangent bundles
Jie Liu, Symplectic singularities arising from contangent bundles
Speaker Jie Liu AMSS I'll report joint works with Baohua Fu (AMSS), in which we investigate symplectic singularities arising from the affinization of the cotangent bundle of a smooth variety.

Progress in Complex Geometry
The goal of the workshop is to INTRODUCE some of the most interesting recent developments in complex geometry to (young) people working in areas related to complex geometry. For this purpose, the speakers will try to make the talks understandable to broad audience. Invited Speakers 2-hours lectures Bin Guo (Rutgers U.) Shigeharu Takayama (U. Tokyo) …
