Domain Theory and Its Applications Seminar Concludes Successfully at Tianyuan Mathematics Research Center
Kou Hui (Sichuan University), Jia Xiaodong (Hunan University)
From December 14 to 20, 2025, the Seminar on Domain Theory and Its Applications was successfully held at the Tianyuan Mathematics Research Center (TYMC). The event brought together 48 scholars from across the globe, whose research focuses on domain theory, non-Hausdorff topology, denotational semantics, topological algebra, logic, and other related fields. Centered on in-depth exchanges regarding domain theory and its practical applications, the seminar aimed to facilitate interdisciplinary dialogue and promote long-term collaborative research among scholars with diverse academic backgrounds.
During the seminar, a total of 16 high-level academic talks were delivered, each lasting approximately one hour—with 50 minutes dedicated to formal presentations and 10 minutes reserved for Q&A sessions and open discussions. Among the speakers, 9 were Chinese scholars, namely Kou Hui (Sichuan University), Li Qingguo (Hunan University), Lyu Zhenchao (Sichuan University), Peng Dekui (Nanjing Normal University), Ruan Xianglong (Shaanxi Normal University), Shen Chong (Beijing University of Posts and Telecommunications), Shi Weixue (Nanjing University), Xu Xiaoquan (Minnan Normal University), and Zhang Dexue (Sichuan University). The remaining 7 talks were given by international scholars, including Matthew de Brecht (Kyoto University), Jean Goubault-Larrecq (University Paris-Saclay), Weng Kin Ho (Nanyang Technological University), Tomáš Jakl (Czech Technical University in Prague), Sebastian Melzer (New Mexico State University), Hannes Thiel (Chalmers University of Technology and University of Gothenburg), and Dongsheng Zhao (Nanyang Technological University). The topics of the talks covered a wide range of cutting-edge research directions, such as function spaces of domains, quasi-metric spaces, power spaces of domains, topological groups, Stone-type dualities, topological properties in non-Hausdorff topology, quasi-Polish spaces, barycentric algebras, canonical extensions, domain structures in operator algebras, and domain models of spaces, among others.
In line with TYMC’s core philosophy of advocating extensive communication, free-ranging dialogue, and in-depth collaboration, the total duration of all presentations was deliberately controlled to no more than half of the overall event time, ensuring sufficient space for in-depth discussions among participants. Through lively and in-depth academic exchanges during the seminar, new cooperative links were established between scholars from home and abroad, laying a solid foundation for future interdisciplinary research.
Notably, Professor Kou Hui announced at the seminar the date and host institution of the 11th International Symposium on Domain Theory and Its Applications. The symposium is scheduled to be held in mid-August 2026 and will be hosted by Sichuan University.
The successful holding of this seminar is attributable to the efforts of the event applicant, Professor Xiaoyong Xi, as well as the generous support provided by TYMC. Special gratitude goes to all staff members of TYMC for their meticulous arrangements, which ensured the smooth progress of the event and made it a fruitful and enjoyable academic gathering.
