2 unusual facts about limit of a sequence


Club set

Thus, if the limit of some sequence in C is less than \kappa, then the limit is also in C.

Harmonic number

The values of the sequence Hn - ln(n) decrease monotonically towards the limit


Dunford–Schwartz theorem

In mathematics, particularly functional analysis, the Dunford–Schwartz theorem, named after Nelson Dunford and Jacob T. Schwartz states that the averages of powers of certain norm-bounded operators on converge in a suitable sense.

Permutation pattern

An unpublished argument of Fred Galvin shows that the quantity inside this limit is nonincreasing for n ≥ k, and so the limit exists.
