SUMMER SYMPOSIUM IN REAL ANALYSIS XXXX
"The Sarajevo - Several Peoples - Single Dream Symposium"

International University of Sarajevo, Sarajevo, Bosnia and Herzegovina
June 19-25, 2016

The 40th Summer Symposium in Real Analysis (The Sarajevo - Several Peoples - Single Dream Symposium) was held at International University of Sarajevo in Sarajevo, Bosnia and Herzegovina from June 19 through June 25, 2016. The symposium's co-directors were Harry Miller and Paul Humke. We would like to thank the International University of Sarajevo, particularly Naida Fetic for her efforts on behalf of the symposium and its participants and Ellie Greiber for helping keep things up to date prior to the symposium.

In addition to the formal mathematical program, time was set aside for research collaboration.
