My main area of interest is span theory, which is a topic in continuum theory. The span X is defined when X is a continuum with a metric on it. Span can be thought of as a continuous analogue of diameter. This concept can be used to study the geometric properties of a space. It can also be used to study the geometric properties of related spaces.
