Shinnosuke Okawa, Semiorthogonal Decompositions and Relative Canonical Base Locus

B236-1 IBS, Korea, Republic of

    Speaker Shinnosuke Okawa Osaka University Motivated by the DK hypothesis, some years ago I proved that SODs of the derived category of a smooth projective variety are strongly constrained by the base locus of the canonical linear system. In particular, this leads to the indecomposability of the derived category of varieties whose canonical

B236-1 IBS, Korea, Republic of

    Speaker Chang-Yeon Chough Sogang Univ. This is an 8 hours long lecture series on algebraic stacks, which have become an important part of algebraic geometry (for example, in the study of moduli spaces) since Deligne and Mumford established the foundation of the theory of stacks. This crash course will be following roughly "Algebraic

Seung uk Jang, Vieta Involutions on Tropical Markov Cubics

B236-1 IBS, Korea, Republic of

    Speaker Seung uk Jang Université de Rennes 1 We discuss the algebraic dynamics on Markov cubics generated by Vieta involutions, in the tropicalized setting, including some introduction to the tropicalization. It turns out that there is an invariant subset of the tropicalized Markov cubic where the action by Vieta involutions can be modeled

Guolei Zhong, Positivity of Tangent Sheaf of Projective Varieties

B236-1 IBS, Korea, Republic of

    Speaker Guolei Zhong IBS-CCG In this talk, we discuss the structure of projective varieties with certain positive tangent sheaves. More precisely, when the tangent sheaf is almost nef or positively curved, we construct a well-defined MRC fibration and study the Fujita decomposition of reflexive sheaves. Besides, we show that the almost nefness of

Yotsutani Naoto, Chow Stability and Non-symmetric Kähler-Einstein Toric Fano Manifolds

B266 IBS, Korea, Republic of

    Speaker Yotsutani Naoto Kagawa University In 2001, Donaldson proved that if a polarized manifold (X, L) admits constant scalar curvature Kähler metrics in c1(L), then (X, L) is asymptotically Chow stable whenever its automorphism group Aut(X, L) is discrete. In this talk, we show that this result does not hold in the case

    Speaker Andreas Höring University of Nice Symmetric holomorphic forms on projective manifolds have been studied from various angles in the last ten years : Brotbek-Darondeau and independently Song-Yan Xie have shown that complete intersections of sufficiently high degree and codimension have an ample cotangent bundle, so many symmetric forms. Vice versa Campana and

    Speaker Grzegorz Kapustka Jagiellonian University We describe a locally complete family of projective irreducible holomorphic symplectic orbifolds as double covers of special complete intersections (3, 4) in P6. This is a joint work with C. Camere, A. Garbagnati and M. Kapustka.
