VUB-Leerstoel lezing

School children are taught the commutativity property in the negative form of what is written in the title. For example 4x5=5x4=20.
This is valid for the standard multiplication of numbers but fails for many other kinds of product, such as for example the product of matrices or the rotation of solids.

Actually, everybody knows that it is not the same to first put on a sock and then a shoe rather than than the other way around.

During this lecture Prof. Dr. Ángel del Río will show examples of non-commutative objects and explain some of the questions on this topic that mathematicians have not been able to solve yet.

After the lecture you are invited to the reception.
