Spectral characterization conjecture. The spectrum of $M=\frac13(a+b+c)$ is the intersection of the line $y=z=1$ with $A$, shrunk by a factor of $\frac13$. This conjecture proposes…

Let $f$ be a quadratic polynomial whose critical orbit is preperiodic, and let its iterated monodromy group be the group obtained from the monodromy actions on the successive itera…
