Dear professor Arcidiacono:

Thank you for the reprint of your paper on “The Theory of Hyperspherical Universes”.

While we have not yet had a chance to study it in depth, even a brief review suggests numerous areas of overlap or complementarity with our efforts. It is of course, those ideas of apparent difference that are the most intriguing and will require more careful attention. Are you familiar with Arthur M. Young’s book, The Geometry of Meaning (published by Delacorte Press/Seymor Lawrence, by arrangement with Robert Briggs Associates, San Francisco, California, 1976)?

With best wishes for your continued efforts in this important work,

Sincerely
Brenda J. Dunne
