The Landau equation introduced by Landau in the 1930's is an important partial differential equation in kinetic theory. It gives a description of colliding particles in plasma physics, and it can be formally derived as a limit of the Boltzmann equation where grazing collisions are dominant. The pur...

It is conjectured that the non-trivial components, known as Kuznetsov components of derived category of coherent sheaves on every quartic double solid is equivalent to that of Gushel-Mukai threefolds. I will introduce special Gushel-Mukai threefold X and its Fano scheme of twisted cubics on it and ...

双有理几何的地理学主要关注代数簇的双有理不变量的分布规律。我们将回顾代数曲线、曲面的地理学分类理论，介绍高维簇的地理学研究现状。
