چکیده
1. Embedding the complete binary tree in low-dimensional `1. Let Tn (Vn , En) be the complete binary tree of height n (so it has 2n+1 − 1 vertices). For two vertices x , y ∈ Vn , let dTn (x , y) denote the length of the (unique) shortest-path between them in Tn . Our goal in this problem will be to nd a map f : Vn → k so that k is small and the map has small distortion in the `1 norm: dTn (x , y) D 6 ‖ f (x) − f (y)‖1 6 dTn (x , y) ∀x , y ∈ Vn . (0.1)

We have seen that if X X1 + · · · + Xn is a sum of independent {0, 1} random variables, then X is tightly concentrated around its expected value [X]. The fact that the random variables were {0, 1}-valued was not essential; similar concentration results hold if we simply assume that they are in some bounded range [−L, L]. One can also relax the independence assumption, as we will see next. Cons...

By Theorem 2.1 the product φ1φ2 is of bounded variation and by Theorem 2.24 all three Riemann–Stieltjes integrals involved exist as the limit of Riemann–Stieltjes sums as |Γ| → 0. In particular we can find a δ1 > 0 such that ∣∣∣∣∫ b a fφ2 dφ1 −RΓ(fφ2, φ1) ∣∣∣∣ < ε , ∣∣∣∣∫ b a fφ1 dφ2 −RΓ(fφ1, φ2) ∣∣∣∣ < ε for all partitions with |Γ| < δ1. Let Γ = {xi}i=0 be any partition of [a, b] with intermed...
