Frontiers in Fundamental Mathematics Research Nexus, 19 Feb

Date/Time: 19 February 2026; 4:00 pm
Speaker: Professor Amnon Neeman (University of Milan)
Title: Vanishing negative K-theory and bounded t-structures
Location: Room 4082, Anita B. Lawrence Centre, UNSW

Join us for this special Nexus colloquium by Professor Amnon Neeman (University of Milan).

About the talk

We will begin with a quick reminder of algebraic K-theory, and a few classical, vanishing results for negative K-theory. The talk will then focus on a striking 2019 article by Antieau, Gepner and Heller — it turns out that there are K-theoretic obstructions to the existence of bounded t-structures.

The result suggests many questions. A few have already been answered, but many remain open. We will concentrate on the many possible directions for future research.

About the speaker

Amnon Neeman is a Professor of Mathematics at the University of Milan where he holds an advanced grant from the European Research Council. He received his PhD from Harvard under the supervision of David Mumford, and then spent four years at Princeton as a postdoc followed by twelve years at the University of Virginia as an associate professor. After this, Amnon joined the Australian National University where he went on to become a full professor, was elected to the Australian Academy of Sciences, and was awarded an Australian Laureate Fellowship. Amnon’s main research focuses on homological algebra and its applications to algebraic geometry, topology, and K-theory. He is especially known for applying novel techniques to the study of triangulated categories, which has resulted in the resolution of important conjectures in algebraic geometry and K-theory.
