报告题目: Sectional curvature of polygonal complexes with planar substructures
时间:3月8日周三下午2:30-3:30
地点:管研楼1518
摘要: In this talk, I will first recall combinatorial curvature
notions of planar tessellations and present global geometric and
spectral results. Then I will introduce "polygonal complexes with
planar substructures", a combinatorial concept comprising both planar
tessellations as well as Euclidean and hyperbolic buildings,
originally introduced by Jacques Tits in Geometric Group Theory.
Finally, I will present global geometric and spectral results for
these discrete spaces. The presented material is based on joint work
with Matthias Keller and Felix Pogorzelski.
