Busemann, Herbert

Herbert Busemann was a mathematician known for his work in geometry, particularly in understanding the shape and structure of spaces. He contributed to the field of metric geometry, which studies geometric properties based on distance, without necessarily relying on traditional notions of straight lines or angles. Busemann's insights helped develop the concept of Busemann functions, used to analyze the structure of non-Euclidean and more abstract spaces. His work provides tools to better understand the geometric properties of complex spaces that appear in areas like physics and computer science.
