Harris, Simon C.; Roberts, Matthew I. The many-to-few lemma and multiple spines. (English. French summary) Zbl 1361.60076 Ann. Inst. Henri Poincaré, Probab. Stat. 53, No. 1, 226-242 (2017). Summary: We develop a simple and intuitive identity for calculating expectations of weighted \(k\)-fold sums over particles in branching processes, generalising the well-known many-to-one lemma.
