R&I Week 2025 - Distinguished Researcher Talk - Dr. Andrew J. Dean

In mathematics, when a class of objects proves to be of interest, the question arises of classifying them somehow. This can mean different things in different cases. The simplest sort of classification is just a complete list of all the objects in the class. This sort of classification may be useful in establishing results on a case by case basis, but it may not provide much information about how the objects are related to each other. A more useful form of classification is to associate to each object a label that captures essential features, while ignoring different guises the same object may appear under. This approach has been extremely successful in the Elliott program to classify certain C*-algebras, and this talk will elaborate on and illustrate it.

Dr. Andrew J. Dean is a professor of Mathematical Sciences at Lakehead University. He is a Lakehead graduate, having completed an HBSc. here before going to the University of Toronto, where he completed a Ph.D. under the supervision of G. A. Elliott. His research deals with C*-algebras and related structures, such as dynamical systems, K-theory, and real structures on C*-algebras. His most recent projects include his collaboration with Dr. Luis Santiago, Classification of real approximate interval C*-algebras, and his work with Lakehead students B. Choi and S.K. Lucky on a range of invariant problems.
