    • The theorem known as the "Leibniz Test," or the alternating series test, tells us that an alternating series will converge if the terms ana_na​n​​ converge to 000 monotonically.
    • Proof: Suppose the sequence ana_na​n​​ converges to 000 and is monotone decreasing.

    • The above examples involving the harmonic series raise the question of whether there are monotone sequences such that f(n)f(n)f(n) decreases to 000 faster than 1n\frac{1}{n}​n​​1​​but slower than 1n1+ε\frac{1}{n^{1 + \varepsilon}}​n​1+ε​​​​1​​ in the sense that:

  • Free Version Control Systems

    • GNU Arch or Monotone (or BitKeeper in the proprietary world).
    • "monotone is a free distributed version control system. it provides a simple, single-file transactional version store, with fully disconnected operation and an efficient peer-to-peer synchronization protocol. it understands history-sensitive merging, lightweight branches, integrated code review and 3rd party testing. it uses cryptographic version naming and client-side RSA certificates. it has good internationalization support, has no external dependencies, runs on linux, solaris, OSX, and windows, and is licensed under the GNU GPL."
