Stochastic Processes and Their Applications The Fields Workshop on Stochastic Processes and Their Applications was held at Carleton University from August 9-11, 2017 under the joint sponsorship of Fields Institute and the School of Mathematics and Statistics of Carleton University. The three-day event featured by two 1.5-hour tutorials, 11 fifty minute invited talks, and 7 thirty-minute short talks given by graduate students. These talks covered a wide range of topics, including Markov processes, queueing networks, stochastic control and filtering, mean field models, stochastic simulations, finance, among others. The materials of the two tutorials were carefully designed to benefit both graduate Workshop on Operator Systems in Quantum Information The Workshop on Operator Systems in Quantum Information was held from August 14 to 17, 2017 at the University of Guelph. There were approximately 40 participants, with roughly half from the surrounding region and half drawn from around the world. Sponsorship was welcomed from the Fields Institute, the Institute for Quantum Computing at the University of Waterloo, and the Perimeter Institute. students and researchers. David McDonald of University of Ottawa presented his tutorial on Yaglom limits, which are concerned with an appropriately defined limiting distribution for an absorbing Markov chain. The second tutorial was delivered by Opher Baron of University of Toronto on queueing and Makov chain decomposition (QMCD). The 11 fifty-minute invited talks covered a diverse range of topics related to probability, stochastic processes, and applications. The event was very successful in bringing together nearly 40 participants and it provided an important forum where researchers and students in the field could meet to encourage on-going research, discuss work-in-progress, and motivate new initiatives.  — Yiqiang Zhao generated new collaborations, the organizers ensured that significant time for scientific discussions was included in the daily schedule. Early indications suggest that once again, plenty of “work” was accomplished at this workshop as well. Participants enjoyed pleasant summer weather in Guelph, with several exploring the university campus and old downtown area. The organizers were delighted to host this workshop and are grateful to all participants for their contributions to the program and discussions, and to the sponsors for their support.  — Jason Crann and David Kribs The purpose of the workshop was to stimulate interaction between researchers with different backgrounds, who are broadly interested in the theoretical development of operator systems and their applications to quantum information. The participants were encouraged to discuss recent developments, modern techniques, as well as the challenges in their respective research programs. The topics ranged from recent theoretical developments such as operator system tensor products and their connection with Connes' Embedding Problem, to modern applications in non-local games, quantum correlations, zero-error quantum channel capacities, quantum error correction, and quantum local operations and classical communication. Building on the format used at a similar workshop last year, of which several participants spoke positively and claimed 23
