Group Action Forum
The Group Action Forum (GAF) is an international mathematical association founded in the year 2002 to form a scientific interdisciplinary forum for mathematicians interested in branches of mathematics where transformation groups appear, and the notion of group and the concept of symmetry both play
important roles. In particular, the focus of the GAF is on group actions in algebra, geometry, topology, analysis, number theory, and mathematical physics. http://gaf.astagor.net/
