Larry Polansky asked me to forward this message about his recent paper "A Mathematical Model for Optimal Tuning Systems" to the Tuning list. I've taken the liberty of cross-posting it to both Tuning and Tuning math as I think it is of sufficient interest for both lists.
Polansky, L.; Rockmore, D; Johnson, K., Repetto, D. "A Mathematical Model for Optimal Tuning Systems," is now posted as 08-05-023 at
