The zero-pole conjecture for topological zeta functions of algebras

Let $\cA$ be a non-associative $\fo$-algebra that is free of rank $d$ as an $\fo$-module, where $\fo$ is the ring of integers in a number field $k$. Zero-pole conjecture. The topological zeta function $\zeta_{\cA,\topo}(\ess)$ has a pole at zero. This is motivated by the apparent analogous pole at zero for meromorphic continuations of local subalgebra zeta functions, although no explanation is known.
