Quasitrace

In mathematics, especially functional analysis, a quasitrace is a not necessarily additive tracial functional on a C*-algebra. An additive quasitrace is called a trace. It is a major open problem if every quasitrace is a trace. (Wikipedia).

Inverse Functions

A graphic and algebraic approach to finding inverse functions. Definition of the Inverse of a Function Let f and g be two functions such that f(g(x)) = x for every x in the domain of g and g(f(x)) = x for all x in the domain of f. Check out http://www.ProfRobBob.com, there you will find
