Packing, Jamming, Freezing.... Computing ! : The hidden link between random satisfiability and the Jamming transition

Florent Krzakala
ESPCI, ParisTech

In this talk I will discuss how apparently unrelated complex problems in different area of science ---how to pack some objects in a given volume, how to color a graph with a given number of colors, understanding why a liquid is turning into a glass when the temperature is lowered, and why some computational problems are hard and some are easy --- actually do share many characteristics, and how by using analogies and by exchanging ideas between these disciplines one can actually make progresses in their studies. The focus will be mostly on the Jamming transition in hard spheres and the associated phenomenology.
