Smarandache Functions

        Several Smarandache Functions, Prime Numbers, and Constants in number theory are presented below.

        The classical Smarandache Function S(n) [ http://mathworld.wolfram.com/SmarandacheFunction.html ] is defined as the smallest integer n such that S(n)! is divisible by n.

        Many extensions and versions of this function have been defined and studied in the meantime, such as: Smarandache Ceil Function, Smarandache Kurepa Function, Smarandache Wagstaff Function, Smarandache Near-to-Primordial Function, Pseudo-Smarandache Function, Smarandache Prime, Smarandache-Wellin Number, Smarandache Prime, Smarandache-Wellin Prime, Smarandache Constants.
