|Real projective manifolds|
|Instructor：||Stephan Tillmann [The University of Sydney]|
|Place：||Conference Room 3, Floor 2, Jin Chun Yuan West Building|
This course begins with an introduction to real projective geometry (projective transformations; cross ratios; duality; projective manifolds;the special role of elliptic, euclidean and hyperbolic geometry). Key notions for the study of convex projective manifolds will then be described in detail (Hilbert metric;isometries; cusps;Busemann functions;horospheres; elementary groups;Margulis lemma). In the last lecture, an overview of what is known about strictly convex projective manifolds is given (thick-thin decomposition; topological finiteness; relative hyperbolicity).
Essential: Courses in Linear Algebra, Abstract Algebra and Metric Spaces.
