Eli Glasner, Tel Aviv University
How to define chaos?

The great popularity of the notion of Chaos attracted many mathematicians to this subject. As a consequence we have today many different interpretations of what a chaotic behaviour should mean. I will discuss briefly several definitions of Chaos in the theory of Dynamical Systems and try to demonstrate, with a few simple examples, how they relate to each other.

Eric Sawyer, McMaster University
The corona problem, the Monge-Ampere equation and two weight inequalities for the Hilbert transform.

We discuss three open problems each with a long history - what has been done with them, what might be done in the near future, and some connections between them.

Ultralimits, Ultraproducts, and Some Open Problems About Groups

The mapping assigning to each convergent bounded sequence its limit has certain natural properties well-known since high school: it is linear, multiplicative (the limit of the product is the product of limits), sends a constant sequence to the corresponding constant value, the limit of a positive sequence is positive, etc. What if one tries to define an assignment of a number, having similar properties, to every bounded sequence (not necessarily a convergent one)? This way, one naturally arrives at the concept of an ultrafilter and ultralimit, and with a little bit more effort, of an ultraproduct of metric structures. We will discuss this construction, as well the role played by it, particularly in group theory, and offer some presently open questions about groups that can be stated in this language.

Final Thoughts: Analysis as a Process

Basically, analysis is the process of taking apart some representation of a situation, and taking it apart to understand how it works. This necessitates a degree of abstraction and the creation of a language to express and manipulate abstract concepts. As mathematics develops and patterns emerge, it becomes desirable to formulate abstract structures and these in turn allow for the cross-fertilization of different areas of mathematics. I will look at a couple of examples.
