SMARANDACHE SERIES by Jose Castillo, Navajo Community College, Tsaile, Arizona, USA A Smarandache Series is any series which involves at least a Smarandache type Sequence, Sub-Sequence, or Function. (Over 200 such sequences, subsequences, and functions are listed in Sloane's database of Encyclopedia of Integer sequences -- online). For examples: a) If we consider the smarandache consecutive sequence: 1, 12, 123, 1234, 12345, ..., 123456789101112, ... we form a smarandache series: 1/1 + 1/12 + 1/123 + 1/4321 + ... . b) If we attach the smarandache reverse sequence: 1, 21, 321, 4321, 54321, ..., 121110987654321, ... to the previous one we get another smarandache series: 1/1 + 12/21 + 123/321 + 1234/4321 + ... . With a mathematics software it is possible to calculate such series to see which ones of them converge, and eventually to make conjectures, or to algebraically prove those converging towards certain constants. The first series is convergent, while the second one is divergent (Ashbacher[1]). Reference: [1] Ashbacher, Charles, "Smarandache Series Convergence", to appear.
