Title: Noncommutative geometry at infinity

Abstract:
In topology, one studies the boundary at infinity of a nice topological 
space in terms of the limit of complements of compact subsets. In 
algebraic geometry, there are at least two different approaches to 
defining the boundary at infinity: via some form of rigid analytic 
geometry (for example, solid algebraic geometry of Clausen-Scholze), and 
another via noncommutative geometry of differential graded categories, 
due to Efimov. We give a unified construction of the boundary at 
infinity compatible with both the analytic and noncommutative points of 
view. We motivate our construction by focusing on an explicit example 
that can be viewed from both topological, symplectic, and algebraic 
points of view, namely that of local systems on the circle. This is 
joint work in progress with Yuan Gao and Yingdi Qin.
