Besikovič, AS (English spelling) BesikovicAS

…The name fractal is related to the Hausdorff dimension, which F. Hausdorff and AS Besikovič discovered around 1919. If we explain only the self-similar figures mentioned above, the Hausdorff dimension is a different dimension that allows non-integer dimensions to be considered, unlike the usual topological dimensions of 0-dimensional points, 1-dimensional lines, 2-dimensional planes, and 3-dimensional solids. As mentioned earlier, line segments are self-similar, but rectangles and rectangular parallelepipeds are also self-similar figures, and if they are divided into N equal parts, the similarity ratio (part/whole) is 1/ N , 1/ N 1/2 , and 1/ N 1/3 . …
