Response to Mutafova-Yambolieva and Sanders.

TO THE EDITOR: My research team and I appreciate the thoughts of Dr. Violetta Mutafova-Yambolieva and Prof. Kenton M. Sanders (VMY-KMS; Ref. 14a) to enhance awareness for our recent paper on -nicotinamide adenine dinucleotide ( -NAD) (17). We agree fully with VMY-KMS that roles for purinergic neurotransmission in the gastrointestinal tract are multiple and can be controversial. Major findings i...

We study the large n limit of the moduli spaces of Gn-instantons on S and CP 2 where Gn is SU(n), Sp(n/2), or SO(n). We show that in the direct limit topology, the moduli space is homotopic to a classifying space. For example, the moduli space of Sp(∞) or SO(∞) instantons on CP 2 has the homotopy type of BU(k) where k is the charge of the instantons. We use our results along with Taubes’ result...

It no longer contained lancets, but small though it was, it was of admirable workmanship and handsome appearance. It bore the following inscription in minute lettering: Presented to J.M.
