Skeleton filtration is a method in algebraic topology that captures the structure of a topological space by examining its skeletons, which are subspaces consisting of points of varying dimensions. This process allows for the analysis of the relationships between these skeletons, helping to construct spectral sequences that arise in the study of algebraic K-theory, particularly in the context of the Atiyah-Hirzebruch spectral sequence.
