 ">Positivity in hyper kahler manifolds via Rozansky—Witten theory</a>\nb
 y Chen Jiang/江辰 (Shanghai Centre for Mathematical Sciences\, Fudan) as
  part of ICCM 2020\n\n\nAbstract\nFor a hyperk\\"{a}hler manifold $X$ of d
 imension $2n$\, Huybrechts showed that there are constants $a_0\, a_2\, \\
 dots\, a_{2n}$ such that $$\\chi(L) =\\sum_{i=0}^n\\frac{a_{2i}}{(2i)!}q_X
 (c_1(L))^{i}$$\n
