论文摘要
我们通过将乔伊斯（Joyce）的同源通用墙壁交叉ARXIV提升：2111.04694将合适的模量堆栈的墙壁隔离为墙壁的墙面框架。主要的新工具是$ \ mathfrak {m} $的操作K-词素是一个模棱两可的乘数顶点代数。
We provide a general framework for wall-crossing of equivariant K-theoretic enumerative invariants of appropriate moduli stacks $\mathfrak{M}$, by lifting Joyce's homological universal wall-crossing arXiv:2111.04694 to K-theory and to include equivariance. The primary new tool is that the operational K-homology of $\mathfrak{M}$ is an equivariant multiplicative vertex algebra.
