**Abstract.**This is the third and last paper in a sequence of three papers on the evaluation of *Beta-function B-splines* (BFBS), the first and second paper in the sequence being [#!d1-2010!#] and [#!d2-2010!#], respectively. This sequence of papers studies explicit representations of BFBS yielding computationally efficient explicit formulae for evaluation of BFBS in terms of polynomial bases used in data interpolation, data fitting and geometric modelling, as well as in the design of multilevel constructions such as, e.g., multiwavelets. While in [#!d1-2010!#] an *interpolatory representation* of BFBS was developed in terms of *local monomial bases*, and in [#!d2-2010!#] a *Bezier-type representation* was derived in *local Bernstein bases*, in the present paper a representation of BFBS in *global monomial bases* is obtained, suitable for use, e.g., in relevance to computing Fourier, Laplace and other transforms in operational calculus.
