TFP Publications

One of Perimeter Institute’s primary objectives is to deliver world-class research discoveries by continuing to focus on advancing fundamental research across Perimeter’s identified areas, encouraging complementary approaches and a collaborative atmosphere which maximizes cross-fertilization and the probability of breakthroughs. The primary means by which new research is communicated to the wider community is through peer-reviewed papers.
