The term "quasitrace" can refer to different concepts depending on the context, particularly in mathematics and functional analysis. In the context of operator theory, a quasitrace is a generalization of the concept of a trace, which is typically associated with linear operators on finite-dimensional vector spaces. A quasitrace often involves a positive functional that exhibits properties similar to a trace but may not satisfy all the properties of a standard trace.
