Singularity-degeneration conjecture for Calabi–Yau zeta functions

Let $R_{\mathbf{v}}(t)$ be the contribution to the zeta function associated with a monomial class $\mathbf{v}$, and define the degree of a rational function by

$$\operatorname{deg}(f/g)=\operatorname{deg}(f)-\operatorname{deg}(g).$$

Singularity-degeneration conjecture. The degeneration of $\operatorname{deg}(R_{\mathbf{v}})$ for each piece of the zeta function of a Calabi–Yau manifold at a singular point in moduli space is determined by the nature of the singularity. The source illustrates this with conifold and other singular loci, but gives no general resolution.
