报告摘要：Let $Q$ be the m-loop quiver. Quantized cohomological Hall algebra and its degenerate version of $Q$ were introduced by Reineke.

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

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