XI International Symposium on Generalized Convexity and Monotonicity

The XI International Symposium on Generalized Convexity and Monotonicity will take place at the Instituto de Matematica Pura e Aplicada (IMPA), in Rio de Janeiro, Brazil, from August 25 to August 30, 2014.

The Symposium is sponsored by the Working Group on Generalized Convexity, and is the 11th meeting in a series which started in Vancouver, Canada, in 1980, and continued in Canton, USA (1986), Pisa, Italy (1988), Pecs, Hungary (1992), Luminy-Marseille, France (1996), Karlovassi-Samos, Greece (1999), Hanoi, Vietnam (2002), Varese, Italy (2005), Kaohsiung, Taiwan (2008) and Cluj, Romania (2011). See the Working Group’s site (www.genconv.org) for more information on other activities.

The symposium will consist of plenary lectures, offered by invited speakers, as well as contributed talks, of 25 minutes each.
