The *International Society for Analysis, its Applications and
Computation* has the acronym **ISAAC**. Analysis is understood
here in the broad sense of the word, including differential
equations, integral equations, functional analysis, and function
theory. It is the purpose of **ISAAC** to promote analysis, its
applications, and its interaction with computation. With this
objective, ISAAC organizes international Congresses for the
presentation and discussion of research on analysis. **ISAAC**
welcomes new members and those interested in joining **ISAAC**
are encouraged to look at the website
http://www.math.udel.edu/isaac/
and
http://www.math.fu-berlin.de/rd/ag/isaac/.

The First **ISAAC** Congress was held at the University of
Delaware, Newark, Delaware, U.S.A. during June 1997. The Second
**ISAAC** Congress was held during August 1999 at Fukuoka
Institute of Technology, Fukuoka, Japan.

As a novelty at the opening ceremony of the second congress ten ISAAC Awards were handed over to those younger mathematicians who where elected by an Award Committee. The awardees were

- Daniele Andreucci (Roma, Italy; pdes, free boundary problems),

The price was equipped with US$ 400.

The award committee consisted of H. Begehr, R.P. Gilbert, M.W. Wong, C.C. Yang

The ISAAC society will continue in encouraging young researchers in analysis, its applications and computation by awarding prices for high quality research at its international congresses.
