The International Centre for Mathematical Sciences (ICMS) was created in 1990 as a collaborative initiative between the University of Edinburgh and Heriot-Watt University. It is at present housed at 14 India Street, Edinburgh, the birthplace of James Clerk Maxwell. ICMS supports research in mathematics in a number of ways. Its most visible activity is the organization of workshops in the mathematical sciences. A distinguishing feature of ICMS's workshop programme is its ability to respond rapidly to current developments in research, organizing workshops of international importance at relatively short notice. The current programme of workshops is supported by substantial grants from EPSRC and the SFC.
