报告摘要：

Let $Q$ be the m-loop quiver. Quantized cohomological Hall algebraand its degenerate version of $Q$ were introduced by Reineke.

In particular,the degenerate cohomological Hall algebra has a nicecombinatorial realization via partitions which has played important role inReineke's approach to DT-invariants of $Q$.

In this talk, we introduce an assoicative algebra $\mathbb{A)$ associated topartitions,which can be viewed as a quantization of the algebra of partitionsdefined by Reineke. It turns out that $\mathbb{A)$ is isomorphic to thequantized cohomological Hall agebra of $Q$. This talk is based on a joint workwith Neil J.Y.Fan and L. Peng.
