dr. andrew j. dean: distinguished researcher talk - "classification problems in mathematics"

about the talk

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.
