HMC Symposium on Pattern Formation

[Robert M. Keller]

			      Harvey Mudd College
			SYMPOSIUM on PATTERN FORMATION
			     February 12-13, 1993

The  symposium will provide a focus on pattern formation from multidisciplinary
vantage points,  particularly  on aspects  of  interest to biologists, computer
scientists,  mathematicians, and physical scientists.   It will examine current
questions in  pattern  formation  within  each  of  these fields  and also with
cross-disciplinary  perspectives.   The  area  of  pattern  formation  includes
formation of both  natural  and  artificial cellular  organisms,  formation  of
patterns on and  within these  organisms, and  space-time growth  patterns.  Of
major concern is  the formation of emergent  patterns  through  the actions and
interactions of many semi-autonomous units,  none of which directs or has  full
knowledge of the overall process.
