_____CHELSEA SCIENTIFIC BOOKS______ "Edmund Landau is a great mathematician and a great expositor of whom the whole mathematical world may be justly proud. His writings perpetuate brilliantly the traditions of Gauss and Weierstrass. This latest book [is] in its crystalline beauty, an inspiration to students of all nations." —•/. F. Ritt, American Math.
