Selfsimilarity, also known as self-similarity or fractal similarity, is a property of certain geometric shapes and mathematical sets where a part of the shape or set is similar to the whole. This concept is fundamental in the study of fractals and has applications in various fields such as mathematics, physics, and computer science.

In mathematical terms, a set is self-similar if it can be divided into parts, each of which is a reduced-size copy of the whole set. This property is often described using the concept of scaling, where the parts are scaled versions of the whole. The scaling factor can be the same for all parts, or it can vary, leading to different types of self-similarity.

Selfsimilarity is closely related to the concept of fractal dimension, which measures the complexity of a fractal pattern. The fractal dimension can be greater than the topological dimension of the space in which the fractal is embedded, reflecting the intricate and often infinitely detailed nature of self-similar structures.

Examples of self-similar shapes include the Sierpinski triangle, the Koch snowflake, and the Mandelbrot set. These shapes exhibit self-similarity at multiple scales, with each part resembling the whole in a recursive manner. The study of selfsimilarity has led to significant advancements in our understanding of complex systems and has found applications in areas such as image compression, data analysis, and the modeling of natural phenomena.
