    Lars, you wrote:

    I can replace the copy of the pdf on the NavList website whenever you wish. It's already "out there" but for "archival" purposes, I can swap in a better version. Maybe wait a few days to make sure there are no other errors...

    You mentioned online translating. Have you tried ChatGPT for translation. I have had excellent experiences with natural language translation. It speaks Swedish and English fluently and can perform translation according to styles you request. Be aware that the interface may require that you upload only five or six paragraphs at a time. ChatGPT is typically smart enough to recognize math and not confuse it with other words in the manner you described. One warning: ChatGPT is a moving target. Its capabilities are not fixed, not necessarily dependable! Try it experimentally.
