yes, thats the common definition here.

I wrote them down long time ago, and I was about to do it again before I discovered this forum.
I dont think proofs were written down already.
But it sounds a very good idea to have these elementary statements safe.
And it should not be too difficult.
So could you do that? I (and I guess the other forum members too) would very appreciate it.
PS: at a[n]1 = a you should add n>1
