In this paper, we define the $K$-theoretic Hall algebra for $0$-dimensional coherent sheaves on a smooth projective surface, prove that the algebra is associative and construct a homomorphism to a redefined shuffle algebra analogous to Negut.

关于曲面的 K 理论霍尔代数

在本文中,我们为光滑射影面上的$0$-维相干滑轮定义$K$-理论霍尔代数,证明该代数是可结合的,并构造类似于Negut 的重新定义的shuffle 代数的同态。
