The function s(u) arising in the study of long primitive BCH codes over GF(q) is reviewed. The set of points 0 < u -< 1 such that qku has a modulo 1 representation in the interval [a, 1] for every integer k >-0 is shown to have Hausdorff dimension s(a) for every 0 \_< a \_< 1.

โฆ Synopsis
Construction of singular fractal functions which are monotonically increasing functions, differentiable almost everywhere and possess nearly zero derivative, is explained based on an iterative technique of distribution of mass onto a line segment, and their graphs are generated using different values of the two relevant parameters. The fractal dimension of the set of points, called the measure's concentrate (where almost the entire mass to be distributed gradually becomes accumulated in successive generations) is found using the result of curdling. The multifractal nature of the measure's concentrate, keeping one parameter unchanged and varying another parameter, is pointed out.

## Abstract Every temperature function with an isolated singularity can be represented as a sum of a temperature function without singularity and an infinite sum of derivatives of a Green function. This generalizes the result of WIDDER on the characterization of positive temperature functions.
