摘        要：We review solid algebra, an approach to homological algebra for complete linearly topologized spaces due to Clausen-Scholze, and explain how it is well-adapted to computing the punctured neighborhood of infinity, as in rigid analytic geometry and in noncommutative geometry as studied by Efimov. This is joint work with Yuan Gao and Yingdi Qin.

报告人简介：Christopher Brav studied at Queen’s University in Kingston, Canada, was a postdoc at the University of Toronto, Leibniz University Hannover, and Oxford University, and worked at the Higher School of Economics and the Moscow Institute of Physics and Technology, before moving to the Shanghai Institute for Mathematical and Interdisciplinary Sciences.
