Hosoya polynomials of the capped zig-zag nanotubes
, 2012 The Hosoya polynomial of a graph G is defined as H (G, x) = Sigma(k >= 0) d(G, k)x(k), where d(G, k) is the number of the vertex pairs at distance k in G.

Hosoya Indices of Bicyclic Graphs [PDF]
, 2009 Given a molecular graph G, the Hosoya index Z(G) of G is defined as the total number of the matchings of the graph. Let Bn denote the set of bicyclic graphs on n vertices.

Solution of polynomial Lyapunov and Sylvester equations
, 2006 A two-variable polynomial approach to solve the one-variable polynomial Lyapunov and Sylvester equations is proposed. Lifting the problem from the one-variable to the two-variable context gives rise to associated lifted equations which live on finite ...

Polynomial Poisson algebras: Gel'fand-Kirillov problem and Poisson spectra [PDF]
, 2014 We study the fields of fractions and the Poisson spectra of polynomial Poisson algebras. First we investigate a Poisson birational equivalence problem for polynomial Poisson algebras over a field of arbitrary characteristic.

Circular Bernstein polynomial distributions [PDF]
This paper introduces a new non-parametric approach to the modeling of circular data, based on the use of Bernstein polynomial densities which generalizes the standard Bernstein polynomial model to account for the specific characteristics of circular ...
