GP name for Ramanujan tau function ?

[Karim Belabas <Karim.Belabas@math.u-bordeaux.fr>]

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.
