But here the word "representation" is being used in a different way that I don't understand, referring to the assertion that the representation is "4-dimensional" and has a given "basis" These words suggest that some vector space is being considered here.

Does anyone happen to know what the fractal dimension of this function is? It's not listed anywhere on the
Internet, but a quick box-counting estimate gives 1.03037, which suggests it could well actually be 1, at least for w=1/2.

I don't think that Hurst parameter should redirect to this page. I was going to add a link from the page on fractional
Brownian motion, but this page is no more about the Hurst parameter than that page is.

I reduced the section "differentiability", that contained wrong and unclear statements. However it may be expanded again hopefully. A more complete exposition should give the modulus of continuity of

Blancmange curve or its integral via various infinite series.

This integral is also self-similar on the unit interval, under an action of the dyadic monoid described in the section
846:. It is "commuting" in that the order of R and g are exchanged with one-another. In this representation, each element
