Entropy and Translation Length in the Ray Graph

Juliette Bavard, Danny Calegari, Alden Walker

Let $Γ$ be the mapping class group of the plane minus a Cantor set, acting on the ray graph $R$ , and for $γ \in Γ$ let $τ (γ)$ denote the translation length of $γ$ on $\mat…

Laminations and External Angles for Similarity Pairs

Danny Calegari, Alden Walker

A {\em similarity pair} is the dynamical system in $C$ generated by two maps $f : z \to sz - 1$ and $g : z \to sz + 1$ for $∣ s ∣ < 1$ . Associated to the dynamical system is an attrac…

Enabling full-speed random access to the entire memory on the A100 GPU

Alden Walker

We describe some features of the A100 memory architecture. In particular, we give a technique to reverse-engineer some hardware layout information. Using this information, we show…

A new proof of the growth rate of the solvable Baumslag-Solitar groups

Jennifer Taback, Alden Walker

We exhibit a regular language of geodesics for a large set of elements of $B S (1, n)$ and show that the growth rate of this language is the growth rate of the group. This provides a…

Conjugation Curvature in Solvable Baumslag-Solitar Groups

Jennifer Taback, Alden Walker

For an element in $B S (1, n) = ⟨ t, a ∣ t a t^{- 1} = a^{n} ⟩$ written in the normal form $t^{- u} a^{v} t^{w}$ with $u, w \geq 0$ and $v \in Z$ , we exhibit a geodesic word re…

Knots in random neural networks

Kevin K. Chen, Anthony C. Gamst, Alden K. Walker

The weights of a neural network are typically initialized at random, and one can think of the functions produced by such a network as having been generated by a prior over some fun…
