By generalising Mobius inversion to finite acyclic directed multigraphs, we show that the coefficients for the reduced Lefschetz invariant of a suitable G-poset of p-subgroups are, essentially, values of a Mobius function. This allows us to present the Knorr-Robinson reformulation of Alperin's conjecture as a case of Mobius inversion. |
