Colloquium – Professor Imre Leader

We are delighted to welcome Imre Leader to the University of Bristol to deliver a Heilbronn Colloquium.

Title: Partition Regular Equations

Abstract: A finite or infinite matrix M is called ‘partition regular’ if whenever the natural numbers are finitely coloured there exists a monochromatic vector x with Mx=0. Many of the classical results of Ramsey theory, such as van der Waerden’s theorem or Schur’s theorem, may be naturally rephrased as assertions that certain matrices are partition regular.

While the structure of finite partition regular matrices is well understood, little is known in the infinite case. In this talk we will review some known results and then proceed to some recent developments.

The talk will not assume any previous knowledge of the area. 

The colloquium will take place in Lecture theatre 2.41, Fry Building at 16:00-17:00 followed by a wine reception in the Fry Common room.

If you would like to attend the talk, please register by filling in this short registration form.
