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.
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 …
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 …

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 …
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.
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) …
Speaker Ilya Kossovskiy SUSTech In this lecture, I will outline convergence and divergence phenomena for mappings of CR submanifolds in complex space. Possible applications for mappings of more general geometric structures will be also concerned.
Speaker Meng Chen Fudan University In this talk, I will present a complete proof for the following theorem: the inequality K3 ≥ 4/3 pg-10/3 holds for all 3-folds of general type.
Speaker Meng Chen Fudan University In this lecture, I will report some new progress in studying moduli spaces of algebraic 3-folds with very small canonical volume.
Speaker JongHae Keum KIAS A smooth projective complex surface S is called a Q-homology quadric if it has the same Betti numbers as the smooth quadric surface. Let S be a Q-homology quadric. Then its cohomology lattice is of rank 2, (even or odd) unimodular. By the classification of surfaces, S is either …
