While adding references in my thesis paper, I copied the following bibtex from google scholar:

@article{bhattacharya2017fuzzy,
  title={Fuzzy independent topological spaces generated by fuzzy $$$\backslash$gamma\^{}$\{$*$\}$ $$ $\gamma$∗-open sets and their applications},
  author={Bhattacharya, B},
  journal={Afrika Matematika},
  volume={28},
  number={5},
  pages={909--928},
  year={2017},
  publisher={Springer}
}

After that I pasted the same in a bib file which I created and then I cited the same in my original tex file. But I am getting the following error in some different line which was compiling just fine earlier. Also I am not able to find any missing '$' sign in that line.

line 48: Display math should end with $$. $$$\backslash
line 48: Missing $ inserted. $$$\backslash
line 48: Display math should end with $$. $$$\backslash$gamma\^{}$\{$*$\}$ $$ $\gamma
line 48: Missing $ inserted. $$$\backslash$gamma\^{}$\{$*$\}$ $$ $\gamma
line 48: Unicode character ∗ (U+2217) not set up for use with LaTeX. ...ackslash$gamma\^{}$\{$*$\}$ $$ $\gamma$∗

Please help me to fix it.

    The title should be Fuzzy independent topological spaces generated by fuzzy $\gamma^{*}$-open sets and their applications

  • remove all the $ , it's not clear what you want but pehaps $\hat{\gamma}*$ $\gamma$-open sets

  • @CarLaTeX I have changed the title accordingly but am still getting the same error message each and every time I try to compile and in the line, it's indicating, I didn't even use display math mode. Also the same line compiled without error before I added this particular reference. Don't know what is wrong actually and I'm stuck.

  • @Usual_Learner Did you run also bibtex? You should run latex, bibtex, latex and latex again to update the bibliography.

Google Scholar is not very good when there's math in the title of a bibliographic item. The “translation” it does is really rubbish.

You need to fix it manually:

  title={Fuzzy independent topological spaces generated by
    fuzzy $\gamma^{*}$-open sets and their applications},

Here's a picture of the article header from the Springer site.

  • Thank you again sir. I have changed the title in the bib file accordingly but still I am getting the same error in line 48 which reads: \textbf{Definition 2.14} \cite{hussain2016weak} Let $F_A$ be a fuzzy soft set in $(X,\tau,E).$ Then $F_A$ is called\\. Here I am not seeing any mistakes.

    @Usual_Learner Sorry, but that's completely unrelated. And I'm afraid to say it shows misusing of LaTeX.

  • Sir what do you mean by misusing of LaTex? Even after I changed the title the error message is still the same and it is showing line 48 again and again but I don't see any error there. Moreover, the same line I compiled before without any error and so I asked.

  • @Usual_Learner Did you run BibTeX again after fixing the .bib file?
