The period map is an important holomorphic map from the moduli space $M_g$ of genus g curves to the moduli space $A_g$ of g-dimensional principally polarized abelian varieties, sending a curve to its Jacobian. It was shown by Farb that the period map is the unique nonconstant holomorphic map from $M_g$ to $A_h$ for h \le g.

In this talk, we will present a Habiro-ring-like object encoding the information of CM points and singular moduli, which may contribute to a Habiro formalism for CM points.
 
We will start with the original Habiro ring defined by Habiro, explain how to view elements in the Habiro ring as power series expansions at roots of unity as well as functions on roots of unity, and sketch Habiro's proof of the injectivity of these associations via congruences of cyclotomic polynomials.
 
We will then recall the theory of s
