## Problem 008 — rank:294

**Title:** Cell-size homeostasis

**Added binding assumptions (LaTeX):**

```latex
Use the law of the explicitly followed daughter, not the population snapshot law. Specify the conditional joint distribution of partition, growth and division variables, including intergenerational dependence. Finite first moments are needed for $W_1$. A stationary-size claim additionally requires an invariant law and a stated recurrence or contraction condition; finite-horizon prediction alone does not establish homeostasis.
