    Many more references and a couple of new sentences in Idea section of logarithmic CFT stub.

    For when the editing functionality is back, to add pointer to fractional-level WZW models understood as logarithmic CFTs:

    with review in:

    • David Ridout, Fractional Level WZW Models as Logarithmic CFTs, 2010 (pdf)

    • Thomas Creutzig, David Ridout, Logarithmic conformal field theory: beyond an introduction, J. Phys. A: Math. Theor. 46 (2013) 494006 (doi:10.1088/1751-8113/46/49/494006, arXiv:1303.0847)

    and of more recent developments:

    • CommentTimeJun 9th 2022

    added (here) a References-section of fractional-level WZW models as logarithmic CFTs

    will split this off as a bare list of references to be re-!include-ed here, so that it can easily be included also elsewhere (notably at WZW model)

    Here is what I am after:

    logarithmic CFT for describing topologically ordered Laughlin-type wavefunctions

    (review in Flohr 2003, §5.4)

    But i need to call it quits for tonight.

    “…in the class of irrational” doesn’t sound like it’s supposed to be the end of the sentence.

    Thanks for the alert. I had not even looked at the Idea-sentences in a long while. They were written by Zoran back in rev 2.

    I have now deleted the first sentence and replaced it by:

    A 2d CFT is called logarithmic (LCFT) if it looks like a rational conformal field theory except that some of the 2-point functions may have a logarithmic dependence on the field insertion, in addition to the usual power law (see, e.g. Fuchs & Schweigert 2019, (8) for a clear account).

    I have now also removed the remaining old sentences from the Idea-section (they seemed a little dubious and in any case not too helpful) and instead added explicit mentioning of the main examples (now here.)
