some bugs in padic BSD

[wuthrich]

Bernadette Perrin-Riou reports two bugs:

One is that this does not work

sage: E = EllipticCurve("91b")
sage: h = E.padic_height(7,10)

The other is that the 2-adic L-series takes gamma to be 1+2 rather than 1+4.

Here is first step, for the padic_height.

I am not able to know what to do for gamma.

trac 20798 using padic_height instead of height

[wuthrich]

That was quick. I did that part myself already and I am working on the other.

[wuthrich]

I modified the code for the p-adic L-functions, both ordinary and supersingular. The error bounds should be correct.

for the bot to run, you need to fill the Author field

good to know, thanks.

[chapoton]

ok, looks good to me
