In math, one often studies random aspects of deterministic systems and structures.  In CS, one often tries to efficiently create structures and systems with specific random-like properties.  Recent work has shown many connections between these two approaches through the concept of "pseudorandomness".  This workshop highlights these connections, aimed at a joint audience of mathematicians and computer scientists.Workshop Homepage: http://www.math.ias.edu/pseudo-workshop/2011Agenda & Abstracts: http://www.math.ias.edu/files/seminars/PseudorandomnessMiniWkshp.pdf
