96 William Langford to Dynamical Systems by Wayne Nagata (UBC), Maciej Krupa (Groningen), Langford, and others; and Hamiltonian Systems and Hamiltonian Bifurcations by Richard Cushman (Utrecht) and Jerrold Marsden. There were two focused workshops: Conservative Systems and Quantum Chaos (October 21–25), organized by Cushman and R.H. Gooding (RAE, U.K.) with a series of lectures by Michael Berry (Bristol) on quantum chaos; and Normal Forms and Homoclinic Chaos (November 8–15; organizers, W. Langford and W. Nagata). The presentations in the latter workshop were collected in Volume 4 of Fields Institute Communications (Normal Forms and Homoclinic Chaos, American Mathematical Society, 1995, ed. W.F. Langford and W. Nagata). In the winter semester, again there were two graduate courses. One was on Global Dynamics, Phase Space Transport, Orbits Homoclinic to Resonances and Applications, presented by Stephen Wiggins (Caltech). While still in residence at the Fields Institute, Wiggins transformed his lectures into a book, which became Volume 1 of the new Fields Institute Monographs series (American Mathematical Society, 1993). The second course was on Dynamic Bifurcations with Symmetry, organized by Martin Golubitsky (Houston) and Ian Stewart (Warwick). It was intended that this course would be developed also into a Fields Institute Monograph. However, when it was nearly written, a computer system crash during a system backup destroyed most of the files for the book. Eventually, Golubitsky and Stewart rescued their research and published it as The Symmetry Perspective: From Equilibrium to Chaos in Phase Space and Physical Space (Birkhauser, 2002). In February 1993, there was a workshop organized by M. Golubitsky, W. Langford, and W. Nagata on Pattern Formation and Symmetry Breaking. Short courses also
