Divisibility,) = .(.) and ..(.) = .(.). We use .(.) for the sum of the . of ., i.e., the positive divisors of . other than . itself, so that .(.) = .(.) - .. The number of distinct prime factors of . will be denoted by .(.) and the total number, counting repetitions, by Ω(.).

Additive Number Theory,greater than . is the sum of . primes and Chen Jing-Run has shown that all large enough even numbers are the sum of a prime and the product of at most two primes. Wang & Chen have reduced the number . to .. ≈ 3.23274 × 10. under the assumption of the generalized Riemann hypothesis.

Diophantine Equations,her with a great number of unsolved problems. There are well-developed theories of rational points on algebraic curves, so we mainly confine ourselves to higher dimensions, for which standard methods have not yet been developed.
