초록본문(Abstract) | Mingo and Popa revealed asymptotic freeness between partial transposes of the Wishart matrices in bipartite situations. This poster is about a follow-up study in the multipartite situation. In $n$-partite system, we can extract particular permutations $\mathcal{E}_{1}, \cdots, \mathcal{E}_{n}$ on $[\pm m]$ from given word with length $m$ composed of partial transposes. Mingo and Popa reached their conclusion via combinatorial arguments about $\mathcal{E}_{1}$ and $\mathcal{E}_{2}$. By employing new combinatorial technics and sharper estimates, we have generalized their results to the multipartite systems, even in a stronger sense of almost sure convergence. Moreover, we exhibit a free central limit theorem for the partial transposes in the asymptotic situation. |
