Triangular sequence of coefficients of an expansion of a tri-degenerate partition of a Bernoulli B(x,n), Chebyshev U(x,n) and a Hermite H(x,n) Sheffer sequence: 1) b(x,t)=t*Exp(x*t)/(Exp(t)-1);; 2) u(x,t)=1/(1-2*x*t+t^2); 3) h(x,t)=Exp(2*x*t-t^2); p(x,t)=b(x,t)*u(x,t)*h(x,t). |

COMMENT

Row sums are:
{2, 27, 484, 11280, 348456, 14589120, 819545280, 59538931200, 5399765562240, 596993441425920, 79100889171494400};
The atomic partition function ( Schodinger wave mechanic solution) is ( of the type):
P(x,y,z,t)=Bessel(x,n)*Fourier(y,m)*Legendre(z,l)*Spin(t,k)
That differential equation solution is basic quantum chemistry.
This partition is a projection of an {x,y,z} solution to a simple {x}.
That is why I call it "degenerate".
In the study of blackbody radiation "actual observation" there is a longer tail than the Bernoulli
distribution would predict ( actually a different curve shape).
That is what actually gave me this sort of idea.
Chebyshev is kind of special relativity velocity like with weight of 1/Sqrt[1-x^2].
Hermite is vibrator like/ oscillator with weight of Exp[ -x^2].
Bernoulli is "boson" like/ radiation and is used for most blackbody calculations
"classically". If you take the Hermite -Chebyshev as being a {3,1} type special relativity like system,
them the surface of a molecule behaving in a relativistic fashion would emit
photons by a partition like this...
This kind of thinking is what is called a physical "model" of a system.

1) b(x,t)=t*Exp(x*t)/(Exp(t)-1) 2) u(x,t)=1/(1-2*x*t+t^2) 3) h(x,t)=Exp(2*x*t-t^2) p(x,t)=b(x,t)*u(x,t)*h(x,t)=sum(P(x,n)*t^n/n!,{n,0,Infinity}); out_n,m=(n + 2)!*n!*Coefficients(P(x,n)).
