Abstract

A 2009 article of Allcock and Vaaler examined the vector space $\mathcal G := \overline{\mathbb Q}^\times/\overline{\mathbb Q}^\times_{\mathrm{tors}}$ over $\mathbb Q$, describing its completion with respect to the Weil height as a certain $L^1$ space. By involving an object called a consistent map, the author began efforts to establish representation theorems for the duals of spaces related to $\mathcal G$. Specifically, we provided representation theorems for the algebraic and continuous duals of $\overline{\mathbb Q}^\times/{\overline{\mathbb Z}}^\times$. We explore further applications of consistent maps to provide representation theorems for duals of other spaces arising in the work of Allcock and Vaaler. In particular, we establish a connection between consistent maps and locally constant functions on the space of places of $\overline{\mathbb Q}$. We further apply our new results to recover, as a corollary, a main theorem of our previous work.
