Figure 15. — The illustration of the persistent Betti numbers $β_{q}^{α, 0}$ and the smallest nonzero eigenvalues of persistent Laplacians $λ_{q}^{α, 0}$ for a regular pyramid. Its base is a square with edge length $\sqrt{2}$ and its height is 2. Important distances are $\sqrt{2} / 2$ , 1, $\sqrt{5} / 2 \approx 1.12$ , $5 \sqrt{2} / 6 \approx 1.18$ and 5/4.
