I can't figure out the meaning of this line in chapter 5.3.4:
This subaddress public spend key is multiplied by the primary private spend key to yield the subaddress public view key:

Because the notations are like below:
PVi = pV0 * PSi

The sentence shows private spend key but the notation is pV0.

Is it a typo?

Yes, it is a mistake. It should read:

This subaddress public spend key is multiplied by the primary private view key to yield the subaddress public view key

  • By the way, in [5.3.4.3 Receiving to a subaddress], Is it another mistake:

    To ascertain whether a given output X (with public transaction key R) was sent to the primary address, the wallet checks calcu- lations based on its the public view key and public spend key.

    Because the notation is in low case: X==Hs(pV0 *R)G+PS0

  • @Mooooo You're right, that's another mistake. All of the algebra in that section is correct, but they said public instead of private where you indicated. – knaccc Mar 23 '20 at 19:09
