A colleague wants to label a graph axis as "Ln(x)". I feel ln should not be capitalized and can't recall seeing Ln elsewhere but can't find an authority to confirm my view (Hart's Rules, TeX documentation, etc). Can anyone point me to a ruling, suggest a killer justification, or quote a counter example? I could imagine seeing, "Ln(x) is the natural logarithm" in a book, but would hope an editor would suggest, "The notation for natural logarithm is ln(x)."
