I don't like the reservations about the system expressed at several points in Chapter 2:
the penultimate par. of 2.5, and the remarks immediately following axiom 2.9.3 (FunExt) and 2.10.3 (UA) about …

I started using grbl with an Arduino diecimila which worked OK for simple shapes (squares, stars) but when I fed it anything complex it would exhibit this behavior. Thinking it was due to the limits …

Implements support for differential forms to Sage. After applying the patch, three new classes are added to sage:
1. `CoordinatePatch` -- an open subset of Rn on which differential forms can be de…

Say I define a hyperelliptic curve and calculate the action of Frobenius \phi on basis differentials w_i. Sage outputs the matrix and f_i such that \phi* w_i = df_i + \sum A_ij w_j.
Then for f_i, in…

The coercion seems to be fine, but the Coleman integral fails:
```
sage: R. = QQ['x']
sage: H = HyperellipticCurve(x*(x-1)*(x+9))
sage: K = Qp(7,10)
sage: HK = H.change_ring(K)
sage: import sage.sc…

sage: p = 71; m = 4
sage: K = pAdicField(p, m)
sage: x = polygen(K)
sage: C = HyperellipticCurve(x^5 + 33/16*x^4 + 3/4*x^3 + 3/8*x^2 - 1/4*x + 1/16)
sage: P =…
