The definition favored by mathematicians ... Another definition, ... the reverse Bessel polynomials ...
The Bessel polynomial may also be defined using Bessel functions ... where ... yn(x) is the reverse polynomial
Please use the same notation for ordinary vs reverse throughout.
- Wolfram uses y for ordinary "y_3(x) = 15x^3+15x^2+6x+1"
- OEIS uses "y_3(x) = 15*x^3 + 15*x^2 + 6*x + 1" for ordinary
- Krall and Frink 1948 says "the Bessel polynomial yn(x)" and lists an ordinary polynomial as increasing powers: "yn(x) = 1 + 6x + 15x^2 + 15x^3"
- Bessel Polynomials by E. Grosswald says "we shall adopt in general the original normalization of Krall and Frink" but then "the reverse polynomial yn(Z)"
- Berg-Vignat 2005 says "θn are sometimes called the reverse Bessel polynomials and yn (u) ... the ordinary Bessel polynomials."
- Campos and Calderón 2011 says "the Bessel polynomial yn (x). ... reverse Bessel polynomials θn (x)"
