Who is the best connected scientist? An empirical study of collaboration networks
Mark Newman, Santa Fe Institute.
April 4th, T-11 Conference Room, TA 3, building 524, room 105, 2:30-4:00pm.
Using data from computer databases of scientific papers in physics, biomedical research, and computer science, we have constructed networks of collaboration between scientists in each of these disciplines. In these networks two scientists are considered connected if they have coauthored one or more papers together. In this talk I will describe various statistical properties of these networks, including time evolution of connection patterns as well as static properties, and suggest a variety of possible ways to answer the question ``Who is the best connected scientist?''
