The concept of a group had been introduced by Galois in his work on the theory of equations and this was followed up by Baron Augustin Louis Cauchy (1789-1857) who went on to originate the theory of permutation groups. Other early workers in group theory were. Arthur Cayley (1821-95) who defined the general abstract mup as we now... 

The methods used to ensure that the Fourier summation does not give a negative electron-density map are mathematical in nature. David Harker and John Kasper in 1948 used the inequality relationships of Augustin Louis Cauchy, Hermann Amandus Schwarz, and Victor Buniakowsky [Buniakovski] (generalized to the Cauchy—Schwarz inequality) to derive relationships between the structure factors (the Harker—Kasper inequalities). These were used by David Harker. John Kasper, and Charlys Lucht to determine the structure of decab-orane, BioH, which was unknown at that time. For this study they...
