The Ninth Pacific Rim Conference on Mathematics (PRCM) will be held at the Darwin Convention Centre, and hosted by the Mathematical Sciences Institute (MSI), at the Australian National University. The conference is a broad mathematical event held every few years that covers a wide range of exciting research in contemporary mathematics. Its objectives are to offer a venue for the presentation to and discussion among a wide audience of the latest trends in mathematical research, and to strengthen ties between mathematicians working in the Pacific Rim region. The conference will provide mathematicians with opportunities to engage with international research leaders, established colleagues, and junior researchers.
