text_A: Prison Break was aired for five seasons from 2012 to 2017.
text_B: See homology for an introduction to the notation .. homology. homology ( mathematics ). Persistent homology is a method for computing topological features of a space at different spatial resolutions .. homology. homology ( mathematics ). More persistent features are detected over a wide range of length and are deemed more likely to represent true features of the underlying space , rather than artifacts of sampling , noise , or particular choice of parameters .. To find the persistent homology of a space , the space must first be represented as a simplicial complex .. homology. homology ( mathematics ). simplicial complex. simplicial complex. A distance function on the underlying space corresponds to a filtration of the simplicial complex , that is a nested sequence of increasing subsets .. simplicial complex. simplicial complex. filtration. Filtration ( mathematics )
