Despite a lot of organizational Corona chaos Annette successfully defended her thesis at KIT this March!
The title of her thesis is:
Contracting boundaries of amalgamted free products of CAT(0) groups with applications to right-angled Coxeter groups
Many thanks to all the locals in Karlsruhe who helped to make this possible.
On March 14 the whole world celebrated its first ever International Day of Mathematics. More than 1000 events were planned in over 110 countries: exhibitions, talks and conferences, artistic and playful activities with families, math trails, special classroom activities, online events and even home celebrations.
