Leképezésekhez

Leképezésekhez is a Hungarian term that translates to "for mappings" or "for representations" in English. In mathematics and computer science, it refers to the concept of establishing a correspondence between elements of one set and elements of another set, or within the same set. This correspondence can take various forms, such as functions, transformations, or projections.

In mathematics, a leképezés is often used to describe a function that maps inputs from a domain to outputs in a codomain. For example, a linear transformation is a type of leképezés that preserves vector addition and scalar multiplication. Geometric transformations like rotations, translations, and scaling are also examples of leképezések, as they map points in space to new positions.

In computer science, leképezések are fundamental to data structures and algorithms. Hash tables, for instance, use a hashing function as a leképezés to map keys to indices in an array, allowing for efficient data retrieval. Graph algorithms often involve leképezések that represent relationships between nodes or edges. The concept is also relevant in areas like image processing, where pixels are mapped to color values, and in database systems, where data is organized and accessed through various mapping mechanisms. The term emphasizes the act of establishing and utilizing these relationships.
