Let Pbe a locally finite poset with the interval space Int(P), and Rbe aring with identity. We shall introduce the Möbius conjugation μ∗sending each function f:P→Rto an incidence function μ∗(f) :Int(P) →Rsuch that μ∗(fg) =μ∗(f) ∗μ∗(g). Taking Pto be the intersection poset of a hyperplane arrangement A, we shall obtain a convolution identity for the number r(A)of regions and the number b(A)of relatively bounded regions, and a reciprocity theorem of the characteristic polynomial χ(A, t)which gives a combinatorial interpretation of the values |χ(A, −q)|for large primes q. Moreover, all known convolution identities on Tutte polynomials of matroids will be direct consequences after specializing the poset Pand functions f, g.
