Description

Content

The course is intended as an introduction to Alexandrov spaces with curvature bounded below. We will go through

•Definitions and examples of Alexandrov spaces with curvature bounded below

•Toponogov's theorem (local-to-global property)
•Maximal diameter and splitting theorems
•Bishop-Gromov inequality and Gromov's precompactness theorem
•Strainers and local geometry of Alexandrov spaces

Completion methods

One can complete the course either by:
•Exercises and course exam or
•Final exam

Learning outcomes

After completing the course the student will

•Understand the definitions of curvature lower bounds in the sense of Alexandrov and can check in easy examples if they are satisfied
•Know the basic ideas behind the proofs of the main theorems presented in the course.

Description of prerequisites

The following courses are preferred but not obligatory
•MATS213 Metric Spaces
•MATS331 Metric Geometry
•MATS111 Measure and Integration Theory 1
•MATS112 Measure and Integration Theory 2
