... corresponding to the divisibility order of the integers . The relationship between the M¨obius inversion formula and Riemann’s zeta function motivates the use of the name “zeta matrix” in the context of a ... nothing but the exponential of the incidence matrix of the Hasse diagram of this poset. We prove that the corresponding M¨obius matrix has a simple expr...

... the sets P and ∅ are R-modular in M. We further know of the following instances of R-submodularity for a matroid M(E, ρ). The first of these was communicated to us by Noble [10]. Recall that the ... networks among others. A primary application of extended submodularity is in the study of Rayleigh properties of the multivariate Tutte polynomial of matroids. Following S...
