👉 Preliminarily, it is a technical term in mathematical analysis and topology that refers to the process of systematically analyzing a set of points or objects. It involves identifying the necessary conditions for a given object to be considered a subset of another set. The goal is to determine whether the two sets are equal, disjoint, or contain the same elements. In simpler terms, preliminarily means to begin by defining and studying a specific topic before proceeding with any analysis or proof.
