Errata (v1.1.1)

Some possible errors in version 1.1.1.

Chapter 3

  • Page 27, Example 19: $\deg(P_5)$ twice
  • Page 28, Example 20: on $P_3(-4)$
  • Page 28, Exercise 25: "from from"

Chapter 4

  • Page 31, it says example XXX
  • Page 41, Algorithm 5: it says example XXX
  • Page 47, Example 45: bugged?
  • Page 47, we have $H_(x_2)$ instead of $H(x_2)$
  • Page 50, "see section4.1.6.1" missing space
  • Page 55, above 4.35 it says "rage" instead of "range"
  • Page 59, Alg. 6, return z instead of return x

Chapter 5

  • Page 73, The discriminant in the snippet is different than E.discriminant()?
  • Page 77, exercise 62, says $E_{5, 2}$ but should say $E_{7, 5}$
  • Page 84, at the top why does it map to $\mathbb{G}2$? Shouldn't it say $E{1, 1}(\mathbb{F}_3)[3]$?
  • Page 84, instead of saying "tangent rule repeatedly" it should say "tangent & chord rules repeatedly"?
  • Page 86, exercise 64, parentheses missing at $[8](0, 1)$
  • Page 95, in eq 5.35 the paragraphs can use \left( and \right)
  • Page 96, above 5.37 it should probably say "Short Weierstrass or Montgomery representation"
  • Page 97, end of 3rd paragraph should be $(-x_1, y_1)$.
  • Page 102, end of exercise 78 should say $alt_bn128(\mathbb{F}_{p^{12}})$
  • Page 103, Example 92, "doing this for 815730721 elements is a bit too slow..."
  • Page 108, top of the page says "add this to references"
  • Page 110, Algorithm 9, should be $y^2 \gets x^3 + a\cdot x + b$
  • Page 119, $y^2 = x^3 + 4^2 + 4 cdot 4^3$, that $4^2$ seems wrong?

Chapter 6

  • Page 135, Example 116 should say $R_{tiny, jj}(<x_1, \ldots, x_n>) = true$.
  • Page 136, Exercise 96, missing double quote at the end
  • Page 138, Example 119 second equation has $m = m$, should say $m = 2$.
  • Page 140, Footnote, says equation XXX
  • Page 152, just above exercise 101, "126implies" space bug
  • Page 158, Eqn 6.15 probably should say $j = 0$ instead of $h = 0$?

Chapter 7

  • Page 177, exercise 103, extra , at the end of line with fn foo.
  • Page 177, exercise 103, in fn main should be in_2 : F.
  • Page 188, "unigned" integer operators
  • Page 193, "We get" at the end of page.
