For my work, I need to check my calculations with an example of a fractal object. I searched on the internet, there are some examples of fractals with their hausdorff dimensions, but no boundary terms related. Also found some 1-d examples, but I need d>3 dimensional objects since my calculations are for BEC. I need a fractal object that its boundary term is known in terms of the volume and the hausdorff dimension. For example, a regular box with lenght L in d-dim, the volume as Ld and the boundary term kL^d-1 (k is a const.) I need such an example for a fractal object or (I don't know if there are any)a regular object with fractal boundary. Maybe I couldn't express very good, but is there any book, paper, method you can recommend about this subject? thanks in advance.
