# The Bulk and the Extremes of Minimal Spanning Acycles and Persistence Diagrams of Random Complexes [Gugan Thoppe, CSA]

The expected weight of the Minimum Spanning Tree (MST) in a uniformly weighted graph on $n$ vertices converges to the constant $\zeta(3).$ Recently, this result was extended to a uniformly weighted simplicial complex, where the role of the MST is played by its higher-dimensional analog: the Minimum Spanning Acycle (MSA). Our work goes beyond and provides a complete description of the histogram of weights in this random MSA as also the death times in the associated persistence diagram.
