Stability of large systems.

H M Hastings

    Bio Systems
    |January 1, 1984

    Summary
    This summary is machine-generated.

    Large systems become more stable with complexity, but competitive and cooperative effects can cause instability. Random matrices in these systems simplify analysis of noise effects.
