51Ackermann function — In recursion theory, the Ackermann function or Ackermann Péter function is a simple example of a general recursive function that is not primitive recursive. General recursive functions are also known as computable functions. The set of primitive… …
52Riemann-Siegel theta function — In mathematics, the Riemann Siegel theta function is defined in terms of the Gamma function as: heta(t) = arg left(Gammaleft(frac{2it+1}{4} ight) ight) frac{log pi}{2} tfor real values of t. Here the argument is chosen in such a way that a… …
53Logarithmically convex function — In mathematics, a function f defined on an convex subset of a real vector space and taking positive values is said to be logarithmically convex if log f(x) is a convex function of x.It is easy to see that a logarithmically convex function is a… …
