A Topological Sorting Criterion for Random Causal Directed Acyclic Graphs

In randomly ordered DAGs, relative counts increase monotonically along causal order, enabling recovery via sorting and yielding singular equivalence classes.

Muon Does Not Converge on Convex Lipschitz Functions

Muon fails to converge on convex Lipschitz functions under any learning rate schedule, though error feedback restores convergence yet harms practical performance. Convex Lipschitz theory therefore poorly explains Muon's practical success, which likely relies on smoothness.
