β¦ Synopsis
Our objective is to exhibit several facts concerning Pfaffians, and their relationship to Schur functions. We adopt the combinatorial point of view that the Pfaffian is a weighted generating function for perfect matchings, in analogy with the definition of the determinant as a weighted generating function for permutations.

<P>Schur analysis originates with a 1917 paper by Schur where he associated to a function analytic and contractive in the open unit disk a sequence, finite or infinite, of numbers in the open unit disk, called Schur coefficients. In signal processing, they are often called reflection coefficients. U
<p><P>The problem of representing an integer as a sum of squares of integers is one of the oldest and most significant in mathematics. It goes back at least 2000 years to Diophantus, and continues more recently with the works of Fermat, Euler, Lagrange, Jacobi, Glaisher, Ramanujan, Hardy, Mordell, A
