Sydney Dynamics Group
SDG workshop: Multiscale dynamical systems - theory and application, Blackheath, Blue Mountains, 2-5 November 2015
The SDG was founded in January 2007 as a cooperation of faculty members between two of the major universities in Sydney, Australia,
the University of New South Wales (UNSW) and the University of Sydney (USyd). The group's research missions span topics in pure and applied
dynamical systems, ranging from algebraic dynamics, ergodic theory,
and Hamiltonian dynamics to rhythms in physiological systems, time
series analysis, geophysical fluid dynamics and statistical
