Notes:
That positivity of all the Karle-Hauptman determinants and the positivity of the electron density in the unit cell are equivalent conditions is well known. A simple way of deriving this result is presented providing at the same time a relation between these determinants and the logarithm of the electron density. The relationship of this logarithm of the electron density to the entropy is also discussed.
