where is the Euler-Mascheroni constant, is the Riemann zeta function, and is the Möbius function (Flajolet and also Vardi 1996, Schroeder 1997, Knuth 1998).
Dirichlet verified the also stronger an outcome that
(Davenport 1980, p.34). Regardless of the divergence of the amount of mutual primes,the alternating series
(OEIS A078437) converges (Robinson and Potter1971), but it is not recognized if the sum
does (Guy 1994, p.203; Erdős 1998; Finch 2003).
There are also classes the sums of reciprocal primes v sign established by congruences top top , because that example
(OEIS A086239), where
(Glaisher 1891b; Finch 2003; Jameson 2003, p.177),
(OEIS A086240; Glaisher 1893, Finch 2003),and
(OEIS A086241), where
(Glaisher 1891c; Finch 2003; Jameson 2003, p.177).
Although diverges, Brun (1919) confirmed that
(OEIS A093597 and A093598).
Consider the analogous sum where, in addition, the terms consisted of must have actually an odd variety of distinct prime factors, i.e., is odd and also . The first couple of such numbers room 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 30, 31, 37, 41, 42, ... (OEIS A030059), which encompass the composite numbers 30, 42, 66, 70, 78, 102, ... (OEIS A093599). Then
(Gourdon and Sebah). The first few terms room then
(OEIS A093595 and A093596).
(OEIS A086242) is additionally finite (Glaisher 1891a;Cohen; Finch 2003), where
|2)lnpsum_(k=1)^infty1/(e^(p^kx)+1) " />|
(Berndt 1994, p.114).
Let be the variety of ways an integer have the right to be composed as a amount of 2 or much more consecutive primes. For example, , for this reason and , for this reason . The succession of worths of because that , 2, ... Is given by 0, 0, 0, 0, 1, 0, 0, 1, 0, 1, 0, 1, ... (OEIS A084143). The complying with table provides the first few such the =k" /> for small .

|3||A067373||240, 287, 311, 340, 371, 510, 660, 803, ...|
Similarly, the complying with table offers the first couple of such the for little .
|OEIS||values that such the |
|1||A084146||5, 8, 10, 12, 15, 17, 18, 23, 24, 26, 28, 30, 31, 39, ...|

Now take into consideration instead the number of ways in which a number have the right to be represented as a sum of one or more consecutive primes (i.e., the exact same sequence as prior to but one larger for every prime number). Amazingly, it then turns out that
