Casson invariant conjecture. The Casson invariant of $\partial(X,o)$ is equal to one-eighth of the signature of the Milnor fiber of $(X,o)$.

Casson invariant conjecture. The Casson invariant of $a3$ equals one-eighth the signature of the Milnor fiber.

Perron's conjecture. The map $\gamma_p$ is a well-defined invariant on $\mathcal{S}^3[p]$. Perron proposed this as an extension of the Casson invariant to the mod-$p$ Torelli group…
