4. Equidistribution of CM points

Problems from the afternoon session of January 29, 2024
    1. Joint equidistribution of CM points

      Problem 4.1.

      [Chris Skinner] Determine the joint equidistribution of CM points over K of products of modular curves over F as \mathrm{disc}(K) \rightarrow \infty.
        • Arithmetic applications of horizontal equidistribution results

          Problem 4.2.

          [Philippe Michel] Let K be an imaginary quadratic number fields. There are equidistribution results for CM points with square-free order of conductor C as C \rightarrow \infty.

          Is there an interesting arithmetic application for this?
              Note: we can ask the same question for similar results in broader contexts.
