Re: The Topos of Music

Prof. Peter Johnstone writes:

While looking for something else, I came across a reference to a recent book called "The Topos of Music: Geometric Logic of Concepts, Theory and Performance" by G. Mazzola, published by Birkh"auser. Has anyone on the categories list seen this book? If so, can you say whether it is really about toposes and geometric logic as I (and most category-theorists) would understand those terms, or is it just a coincidence of terminology?

I've not yet seen the book, but I have looked at some of the related web sites. It is not "just a coincidence of terminology", though I don't understand if the usage of toposes, geometric logic, algebraic geometry, etc. is more than alegorical. -- Bob
