The parallel worlds of number theory
Inaugural lecture delivered on 15 August 2013
Florian Breuer was born in 1977 in Vienna, Austria, to German parents and moved to Stellenbosch at the age of 4, where he grew up and completed his undergraduate studies at Stellenbosch University in 1998. He then moved to Paris on a French Government Scholarship, where he completed his Ph.D. in 2002 at the Universit e Denis Diderot under supervision of Marc Hindry. After postdoctoral positions at the National Center for Theoretical Sciences in Hsinchu, Taiwan (2003) and at the Max-Planck-Institut f ur Mathematik in Bonn, Germany (2004), he returned to Stellenbosch University as a Senior Lecturer in July 2004. He was promoted to Associate Professor in October 2007, and to Professor in January 2013. He serves as the head of the Mathematics Division in the Department of Mathematical Sciences since 2012. In 2007 Florian was awarded the Meiring-Naud e Medal by the Royal Society of South Africa, and in 2009 he spent six months at the University of Kassel, Germany and at the ETH-Z urich, Switzerland, with an Alexander-von-Humboldt-Fellowship for Experienced Researchers. In 2011 Florian was invited onto the editorial board of the Journal of Number Theory and in 2013 he was featured amongst the Mail&Guardian's \200 Young South Africans". Florian is particularly proud of the fact that for the last three years, a top rst-year student has nominated him as his most inspiring lecturer at the First Year Academy's Prestige Dinner. In his spare time, Florian is an award-winning landscape photographer. He lives in Stellenbosch and is married to Erica Breuer.
