I tried to understand Brun's original combinatoric treatment of Brun Sieve.
(Unfortunately, I do not understand German), so I could not read Brun's original paper as in following:
Viggo Brun (1915). "Über das Goldbachsche Gesetz und die Anzahl der Primzahlpaare". Archiv for Mathematik og Naturvidenskab B34 (8).
Many books on Sieve talk about Brun Sieve, but they all seems not follow as much "combinatoric nature" of the original Brun's ideas.
According to Erdos, Brun Sieve is the MOST important elementary number theory method.
Can anyone point a link of introduction to Brun's Sieve which followes Brun's original combinatorial approaches ?
Thank you.
