Luitzen Egbertus Jan Brouwer (27 February 1881 – 2 December 1966), was an influential Dutch mathematician and philosopher, who worked in topology, set theory, measure theory and complex analysis. On December 2, 1966 Brouwer died as a consequence of a traffic accident. Brouwer had by then put his ever-lasting mark on mathematics, logic and philosophy. In mathematics he revolutionized topology with his dimension theory, fixed point theorems and homotopy theory. In logic he became the founding father of intuitionism, with its constructive approach to mathematics and logic that is also relevant in theoretical computer science. In philosophy he questioned our very perception of mathematical reality.
On December 9, 2016, there has been a one-day symposium at the Science Park 125 (entrance next to CWI) in Amsterdam:
"L.E.J. Brouwer, fifty years later"
with an interesting programme and highly renowned speakers, viz.
Dirk van Dalen, Mark van Atten, Sergei Artemov, Alexander Dranishnikov, Saul Kripke, Yiannis Moschovakis, Michael Rathjen, and Raf Bocklandt.
The presentations of Sergei Artemov and Saul Kripke can be found on youtube:
The symposium was organized under auspices of the KWG and financially supported by these organizations. Scientific committee: Dirk van Dalen, Jan Willem Klop, Jan van Mill and Geurt Jongbloed.
