Formulas derived from moment generating functions and Bernstein polynomials

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.

Moment Generating Functions

1 Generating Functions 1.1 The ordinary generating function We define the ordinary generating function of a sequence. This is by far the most common type of generating function and the adjective “ordinary” is usually not used. But we will need a different type of generating function below (the exponential generating function) so we have added the adjective “ordinary” for this first type of gene...

Generalized Bernstein Polynomials and Symmetric Functions

We begin by classifying all solutions of two natural recurrences that Bernstein polynomials satisfy. The first scheme gives a natural characterization of Stancu polynomials. In Section 2, we identify the Bernstein polynomials as coefficients in the generating function for the elementary symmetric functions, which gives a new proof of total positivity for Bernstein polynomials, by identifying th...
