Summary: We describe the relation between graph decompositions into walks and the normal ordering of differential operators in the \(n\)-th Weyl algebra. Under several specifications, we study new types of restricted set partitions, and a generalization of Stirling numbers, which we call the \(\lambda\)-Stirling numbers.
