The logarithmic function is f(x) = log b(x). The constant “b” is the base of the logarithm. Another way to understand this concept is when graphing both a logarithmic function and the inverse ...

Consider a function F (X, Y) of pairs of positive matrices with values in the positive matrices such that whenever X and Y commute F (X, Y) = X p Y q. Our first main result gives conditions on F such ...
