Title: Local Analytic Geometry
Time, Day and Date: 12:30 p.m., Tuesday, September 3
Venue: Room 215, Department of Mathematics
Abstract:
LAG is mainly local study of complex analytic varieties. So it is useful for understanding algebraic varieties in a small Euclidean neighborhood of a point. Some part of the theory is just local algebra, particulaly local analytic rings. The theory is quite nontrivial and rich because of results of Cartan, Hamm, Hironaka, Milnor, Mumford, Oka, Remmert, Scheja, Stein, Thullen, Le dung Trang, Whitney,....It is important for singularity theory, from analytic, geometric, and topological viewpoints. No sheaf cohomology is used.
