# Extension of the $\nu$-metric

@article{Ball2010ExtensionOT, title={Extension of the \$\nu\$-metric}, author={Joseph A. Ball and Amol Sasane}, journal={arXiv: Optimization and Control}, year={2010} }

We extend the $\nu$-metric introduced by Vinnicombe in robust control theory for rational plants to the case of infinite-dimensional systems/classes of nonrational transfer functions.

A new sufficiency proof for the Nyquist criterion is obtained via the analyticity properties of the log function. The intuition derived therefrom is then used to formulate a generalized stability…
