If x = y (that is, x and y are the same word), then x and y will not differ in any entry, in which case d(x, y ) = 0. However, if x 6= y , then x and y will differ in at least one entry, so d(x, y ) > 0. We have the ...

These applications relate to prime ramification, the finiteness of the class number, cyclotomic extensions, and the unit theorem. Finally, we present an exposition of the class number formula, which generalizes ...
