Dear Colleagues - participants of W04 Workshop on: Large Scale Nonlinear and Semidefinite Programming This email is to all the participants/speakers. We have a preliminary schedule at: http://orion.math.uwaterloo.ca/~hwolkowi/w04workshop.d/wphotos.d/preschd.html linked from the workshop web page at: http://orion.math.uwaterloo.ca/~hwolkowi/w04workshop.d/readme.html As noted on the schedule, there will be a poster session held throughout the four days of the short course and the workshop. We have received too many excellent contributed talks and do not have enough slots for everyone. If you are on the list of speakers, then please tell us ASAP if you cannot attend. If you are not on the list, then we hope that you will still attend. Please tell us if you would like to join the poster session. Our budget includes breakfast/lunch/banquet for all participants. Please tell us if you will NOT attend.
