The Extended Objects of String Theory

Page 524, Eqs. (19.4): both are wrong (compare with Eqs. (16.48)) and should be replaced by

$ℓs = (-ℓ(P1l1)anck)3∕2∕R110∕2 , gA = (R10 ∕-ℓ(1P1la)nck)3∕2 . (19.4)$
Page 526, Eqs. (19.17): T-dualizing the mass of the S9-brane one gets the mass of the KK9A, which is

$R3R8 ⋅⋅⋅R1 R3 MKK9A = -9--4-12---, TKK9A = ------99--4-3. (19.17 ) gAℓs (2π ℓs)gA ℓs$
Page 527, Table. (19.1): the mass of the D8 brane in 11-dimensional language should be

$3 -(11) -12 R 10R9 ⋅⋅⋅R2 (ℓPlanck)$
Page 527, Table. (19.1): the mass of the KK9A brane in 11-dimensional language should be

$R3 R8 ⋅⋅⋅R1 (-ℓ(11) )- 12 9 Planck$
Page 528, Table. (19.3): the mass of the KK9M brane should be

$3 -(11) -12 R 10R9 ⋅⋅⋅R2 (ℓPlanck)$
Page 545, Eq. (19.83): the first exponent is 2, not 12

$2 2 2 2 1- N dr + (1 - N∕12 ) r dθ , r = |ω| 12∕(1 - N ∕12),$
Page 556, Eq. (19.111): the matrix ₀ should not appear inverted in the formula, which should read

$∘ -------- (2π-ℓs)7ℓsˆg3∕2 T ˆ hpq1 = 6ω ⃗q M0 ⃗q . (19.111 ) (7)$
