And Nicholas Crawford

Recently, a random current representation for transverse field Ising models has been introduced in [15]. This representation is a space-time version of the classical random current representation exploited by Aizenman et. al. [1, 3, 4]. In this paper we formulate and prove corresponding space-time versions of the classical switching lemma and show how they generate various correlation inequalit...

Crawford Williamson Long *

I do not propose this evening to delve into the age-old argument concerning the discoverer of anesthesia. It is doubtful if any here assembled have, to any very great extent, witnessed surgery without anesthesia, yet only 100 years ago the screams of agony issuing from the operating room would have chilled the blood of the hardiest among us. The important point of this contribution is not which...

Maclyn McCarty (1911–2005)

While attending the theater with friends, one of the many activities that he enjoyed, he collapsed. “Dr. Mac” was revered worldwide for his remarkable experiments that led to the identification of DNA as the genetic material. This totally unanticipated discovery, and the revolutionary 1944 paper ...

Robert Macpherson and Arithmetic Groups

We survey contributions of Robert MacPherson to the theory of arithmetic groups. There are two main areas we discuss: (i) explicit reduction theory for Siegel modular threefolds, and (ii) constructions of compactifications of locally symmetric spaces. The former is joint work with Mark McConnell, the latter with Lizhen Ji.
