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


• The title should be Fuzzy independent topological spaces generated by fuzzy $\gamma^{*}$-open sets and their applications Jan 22 at 22:47
• remove all the $ , it's not clear what you want but pehaps $\hat{\gamma}*\gamma$-open sets Jan 22 at 22:48 • @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. Jan 22 at 23:27 • @Usual_Learner Did you run also bibtex? You should run latex, bibtex, latex and latex again to update the bibliography. Jan 23 at 9:02 1 Answer 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. Jan 22 at 23:02
• @Usual_Learner Did you run BibTeX again after fixing the .bib file? Jan 23 at 9:15
