## Graduate Colloquium - Joint Math Seminar of ETH and UZH

Welcome to the new Graduate Colloquium, the "**What is**..." series of talks (borrowing the idea from the articles in the Notices of the AMS). It is a joint seminar of **ETH** and **UZH**, which takes place alternating with the Zurich colloquium in Mathematics. Choose your favorite topic to talk about: one of the first basic interesting things that you had to learn to begin approaching your thesis problem, or something that you found fascinating and want to share with other people. If, on the contrary, you want to hear about a particular topic, don't hesitate to contact one of the organizers.

The Graduate Colloquium is an informal seminar aimed at graduate students and postdocs whose purpose is to provide a forum for communicating one's interests and thoughts in mathematics. The talks including questions are usually one hour, so that there is plenty of room for private discussions afterwards.

Let us make this colloquium a regular meeting point for the student and postdoc members of the Zurich Graduate School! Most of all, volunteer to give a talk!
