| Re: GP name for Ramanujan tau function ? |
Hello list,
I'm looking for a good name for Ramanujan tau function, giving the
coefficients of the Delta modular form.
tau() : no; would break scripts using Greek letters as variables...
taudelta() : better, but not that clear
tauramanujan() : my current personal favourite
( rather than ramanujantau() )
The intent of the function is to compute tau(n) for a *single* value n,
in time n^(1/2 + epsilon).
Another related function could return [tau(n) | n <- [1..N]]
tauramanujanvec() ?
But I don't think it's that useful since the implementation
[ from x * eta(x)^24 ] is trivial.
The soon-to-be-released L-function package also allows to play with
L-series (which includes returning their coefficient list up to some
bound, but NOT an individual coefficient).
Ideas / Opinions anyone ?
Cheers,
K.B.
