YESS-4, Day 5

At the 5th day of the YERME Summer School, Günter Törner is going to deliver the main lecture. His topic is "theory versus practice", and you can learn more from the paper that is published on the YESS-4 website.

Törner has published a multitude of papers and books in mathematics (algebra, geometry and discrete mathematics) as well as mathematics education. Several of them are available on his website, so take a look at the links I just gave you!
