2018年5月20日，2003网站太阳集团邀請美國Louisiana State University，Jimmie Lawson教授來校作“The relation between order and topology”報告。報告在2003网站太阳集团9-309學術報告廳舉行，院長歐陽自根主持報告會。學院部分老師和研究生參加并認真聆聽了此次報告。

在報告會上，Lawson教授首先介紹了非Hausdorff拓撲的背景以及研究意義，從實數出發介紹了序結構和T0拓撲之間的相互生成方式。而對于偏序集上最重要的兩種拓撲：Scott拓撲和Lawson拓撲(以Lawson教授名字命名)，教授介紹了它們産生的動機和具體形式。一方面偏序集的結構決定了這些拓撲，另一方面這些拓撲的又能很好的反映原來偏序集的特殊性質。最後，Lawson教授就該方向的熱點以及今後的發展趨勢做了點評，給相關老師提出了具體的建議。
