Alpha Magnitude

Explore the concept of alpha magnitude in this 40-minute conference talk by Miguel O'Malley from the Applied Algebraic Topology Network. Delve into the world of isometric invariants for metric spaces, starting with the introduction of magnitude by Leinster in 2010. Discover how persistent magnitude, developed by Govc and Hepworth, paved the way for the novel concept of alpha magnitude. Learn about the key properties of alpha magnitude and its computational advantages over traditional magnitude and Rips magnitude. Examine heuristic observations and a conjecture relating alpha magnitude to the Minkowski dimension of compact subspaces in Euclidean space. Gain insights into how alpha magnitude can be applied as an efficient measure for estimating fractal dimensions in real-world data sets, offering a practical tool for researchers and data scientists working with complex metric spaces.
