Silke Meißner (TU Darmstadt): Simplicity of the Automorphism Groups of Some n-Order Expansions

Thursday, 05.11.2020 10:30 im Raum via Zoom

Mathematik und Informatik

In [1] it was shown that the automorphism groups of (1-)order expansions of several homogeneous structures with a stationary independence relation are simple. We follow the basic approach from [1] in order to show that the same holds true for n-order expansions, 1 < n. However, the passage from 1-orders to n-orders causes some extra challenge that requires a different proof idea. My proof involves a reduction of the problem to 1-orders that comes, in return, with significant constraints we have to deal with. [1] F. Calderoni, A. Kwiatkowska, K. Tent.
