COMMENTS

These rational polynomials R(n;x) appear in the evaluation of an integral in thermal field theories in the Bose case. See the Haber and Weldon reference eq. (D1), l. 2, p. 1857 and the W. Lang link.

FORMULA
|
a(n, m)= numerator(R(n, x)[x^m]), m=0, ..., n-1, n>=1, with the rational polynomials R(n, x) of degree n-1 defined by R(n, x):=hypergeom([1, 1, 1-n], [3/2, 2], -x/2)) = sum(R(n, m)*x^m, m=0..n-1), n>=1.
The rational polynomials are R(n, x) = 1 + sum(binomial(n-1, m)/((m+1)*(2*m+1)*binomial(2*m, m))*(2*x)^m, m=1..n-1), n>=1.
a(n, m)=numerator(R(n, m)) with R(n, m) = binomial(n-1, m)/((m+1)*(2*m+1)*binomial(2*m, m))*2^m, m=1..n-1, n=1, 2, ... and R(n, 0)=1, n>=1, else 0.
