Low-rank hypothesis of complex systems

A 57-slide introduction to dimensional reduction and low-rank structure in complex networks and ecosystems.

High-dimensional systems often display behavior controlled by a much smaller number of collective directions. This talk develops the idea that low-rank structure can provide a useful organizing principle for complex networks and ecosystems.

What the slides explore

  • Why dimensional reduction can work in complex systems
  • Low-rank representations of high-dimensional interactions
  • Collective variables and effective descriptions
  • Examples motivated by complex networks and ecosystems

The deck is intended as a visual introduction to the hypothesis and the questions it suggests, rather than a self-contained technical paper.
