Workshop on Diophantine Geometry Related to the ABC Conjecture. The University of Arizona, Tucson AZ March 14-18, 1998 http://www.math.arizona.edu/~SWCenter/aws98/FirstAnnouncement.html ----- The Arizona Winter School: This conference is the first Arizona Winter School on Arithmetical Algebraic Geometry. The goal is to expose graduate students and young researchers in number theory and algebraic geometry to current topics in arithmetic geometry in a short span of time, and in an intense interactive environment with the presence of experts in the field. There will also be a professional development component which is intended to provide an opportunity for young researchers to acquire practical skills relevant to their careers. Topics for 1998: The topic for this first year is `Diophantine Geometry related to the ABC conjecture.' A series of survey lectures will be delivered by D.W. Masser and numerous talks of both introductory and specialized nature are planned. The focus of the professional development component will be the teaching of mathematics. Perspectives from mathematics education research and from the classroom experience of mathematicians will be presented. The component will include roundtable discussions by participants as well as lectures. Organizers: Alexandru Buium, Minhyong Kim, and Felipe Voloch Confirmed Speakers: A. Buium, H. Darmon, D.W. Masser, B. Mazur, L. Szpiro, P. Vojta, and F. Voloch Further Information: See the web page http://www.math.arizona.edu/~SWCenter/ or send a message to majordomo@swc.math.arizona.edu with "subscribe aws98" in the body.
