If we check the limits of the ratio of the gamma function and the 3rd and 4th hyperoperators (exponentiation and tetration), then we see the the gamma function should be an interoperator. I show it: lim exp(h) / h! = 0 lim h! / h^^2 = 0 lim h!^(1/h) / h = 1/e lim log(h!)/log(h) / h = 1 h->+oo I guess the level of iteration of an analytic increasing function, operator depends on its limits at infinity as also its asymptote at infinity. It is important to investigate the higher- and interhyperoperators. Now, I would like to generate the functional inverse of the gamma. I have used matrices Carleman. Code:Dfac(x,N,h)=intnum(t=0,h,t^x/exp(t)*log(t)^N) /*Nth derivative of function gamma*/ n=11 A=matrix(n,n,i,j,Dfac(0.0,j,1000.0)^i/j!) defac(x)=sum(k=0,n,(A^-1)[1,k]*x^k) I checked if defac(24)=4, but no, it does not work. Please, help me. Best regards, Xorter Unizo Xorter Unizo « Next Oldest | Next Newest »
