“**Generalized Concavityin Optimization and Economics”**

**Vancouver (Canada)****August 4-15, 1980**

The 1st International Symposium on Generalized Convexity and Monotonicity was held at the University of British Columbia in Vancouver (Canada), from 4 to 15 of August, 1980. About 100 participants from 15 different countries attended the conference and over sixty lectures were given.

This was a NATO Advanced Study Institute (ASI), which lasted two weeks. The proceedings constitute the first volume devoted to Generalized Convexity. This sizable book (767 pages) by Academic Press is now out of print (the first textbook on the subject appeared much later, but it was begun before this conference; see Avriel, M., Diewert,W.E., Schaible, S. and I. Zang, Generalized Concavity, Plenum Publishing Corporation, New York, 1988).
