Aspects of topoi: Corrigenda and acknowledgements

Abstract

“Aspects of Topoi” [1] appeared in July 1972 through the Herculean efforts of Bernard Neumann with the able assistance of Tim Brook and Max Kelly. The original manuscript was written in haste during the last two weeks of the author's visit to Australia. Somehow just five months later it appeared in print. Among the difficulties surmounted was a set of page proofs which having been sent via slow steamer by the U. of Penn. administration arrived after the paper was in press.
