Abstract
This document offers a concise introduction to the mathematical theory and practical application of the Hausdorff Measure and Dimension. The primary objective is to clarify and rigorously detail the two most common methods used for calculating the dimension of a set, ensuring all calculation details are transparent for the reader. The paper first establishes the theoretical groundwork by reviewing the definitions of the Hausdorff measure, proving the dimensional invariance under changes to the shape of the covering sets, and confirming the dimensional property of open sets. It then introduces the two main methodologies. The first is the Lower and Upper Bound Estimation, which uses the relationship between the measure and the dimension . This method emphasizes the use of the Mass Distribution Principle for establishing the lower bound, which is essential when…
