to be held in Pisa (Italy), June 2002

This is to inform you that both the special session and the satellite conference on


to be held in Pisa, June 10-16, 2002, have been confirmed.

The segment from June 12-16, 2002 is a joint meeting of the UMI (Italy) and AMS (United States); the segment from June 10-11 is a satellite meeting that we have added to meet the anticipated demand (based on replies to our earlier announcement).

The meeting's description (from the conference application) is reproduced below.

Up-to-date news on the "NS2002" can be found on the web-site:.

(Please note that this address has changed from the earlier announcement. If that site doesn't work, try here.)

It is intended that people willing to participate to the "NS2002" must register for the AMS-UMI meeting and pay the conference fee. In particular, for all logistic information (including accommodation) they should visit the AMS-UMI site at:

(A link to the NS2002 will be put on the AMS-UMI web site).


In the registration form of the AMS-UMI meeting, people willing to participate in the NS2002 must indicate "Nonstandard methods and applications in mathematics" as their special session of interest. When you have registered, please let us know directly with an email to:

You will receive a more precise announcement in a few weeks, including a tentative program and list of invited speakers. However, we urge you to take the above deadline into account before opting to wait for that announcement.

Please circulate this announcement to anyone you think might be interested.

We look forward hearing from you.

(from the application for the AMS/UMI special session)

Nonstandard analysis is arguably the greatest single achievement of applied mathematical logic in the last half-century. Besides the important philosophical achievement of providing a sound mathematical basis for using infinitesimals in analysis, the methodology is by now well proven both as a research and teaching tool as well as being a fruitful field of investigation in its own right. It has been used to discover and prove significant new standard theorems in such diverse areas as probability theory and stochastic analysis, functional analysis, dynamical systems and control theory, and recently there have been some striking and unexpected applications to additive number theory.

The achievements of nonstandard analysis can be summarized under the headings: (i) explanation - giving fresh insight or new approaches to established theories; (ii) discovery - leading to new results in diverse fields; (iii) invention - providing new, rich structures that are useful in modeling and representation, as well as being of interest in their own right.

While the fields of application of nonstandard analysis are diverse, the common methods and ideas make it appropriate to devote a special session to these methods and recent developments and applications. The topics and contributions will range from foundational questions (including those arising from different approaches to nonstandard analysis) to recent results and the discussion of potential future developments.
