چکیده

In this paper, we generalize the classical Bonferroni inequalities and their improvements by Galambos to sums of type ∑ I⊆U (−1)|I|f(I) where U is a finite set and f : 2 → R. The result is applied to the Tutte polynomial of a matroid and the chromatic polynomial of a graph.

Tutte polynomials of wheels via generating functions

We find an explicit expression of the Tutte polynomial of an $n$-fan. We also find a formula of the Tutte polynomial of an $n$-wheel in terms of the Tutte polynomial of $n$-fans. Finally, we give an alternative expression of the Tutte polynomial of an $n$-wheel and then prove the explicit formula for the Tutte polynomial of an $n$-wheel.

BONFERRONI-TYPE INEQUALITIES; CHEBYSHEV-TYPE INEQUALITIES FOR THE DISTRIBUTIONS ON [0, n]

Abs t rac t . An elementary "majorant-minorant method" to construct the most stringent Bonferroni-type inequalities is presented. These are essentially Chebyshev-type inequalities for discrete probability distributions on the set {0, 1 , . . . , n}, where n is the number of concerned events, and polynomials with specific properties on the set lead to the inequalities. All the known resuits are ...

Chromatic polynomials of some nanostars

Let G be a simple graph and (G,) denotes the number of proper vertex colourings of G with at most  colours, which is for a fixed graph G , a polynomial in  , which is called the chromatic polynomial of G . Using the chromatic polynomial of some specific graphs, we obtain the chromatic polynomials of some nanostars.
