LyX ⇒ Bibliography sorting order and max number authors

[alfredospuri]

Hi all, I am writing my PhD thesis and have been trying to get my bibliography in the format i want but i can't seem to manage. I attach both the LyX file and the bib file. The problems are the following:

1: I do not manage to fix the max number of authors in the bibliography, not even using the maxbibnames option.
2: I do not manage to make the bibliography items be displayed in order of citation. They seem to keep the order in which they are written in the bib file. I tried all possible style combinations, adding the \renewcommand\bibliographystyle{unsrt} and other options but it never gets solved.

For further reference, I use JabRef for building the bibliography file and LyX version 2.3.7.

I would be extremely grateful if anyone managed to help me with this. Thanks a lot!
