In my Overleaf document I created a .bib file with Overleaf-supported syntax (on Overleaf I always use \usepackage[backend=biber, style=alphabetic, sorting=ynt]{biblatex}), but when I copy my .bib file into TexStudio, this editor doesn't succed in read that .bib file.
I found motivation: Overleaf syntax is bitty different with respect TexStudio one.
Is possible to convert a .bib file for Overleaf in .bib file for TexStudio? OR, does exist another way to solve my problem?
Thanks in advance
First Edit: I use pdfLatex distribution and I setted Biber as indicated to myself in your comments. My problems are: citation undefined, why?
If it can be of use to you, the code of my .bib file (named Frobenius.bib)

.bibsyntax is always the same no matter which editor you use. There are subtle differences between the meanings of fields etc. when you change betweenbiblatexor BibTeX (or indeed between different BIbTeX/biblatexstyles), but that should usually not lead to errors. It's more likely that your local setup with TeXstudio is not exactly the same as Overleaf. Overleaf runslatexmkwhich can run Biber etc. for you automatically. Locally you may have to configure your editor to run Biber for you https://tex.stackexchange.com/q/154751/35864. – moewe Mar 09 '24 at 16:53https://en.wikipedia.org/wiki/Sheaf_(mathematics)?
