I notice that Jean-Louis Loday's personal web page is not accessible any more. It used to have slides from a talk that Loday gave in 2012 on "combinads". The link to these slides was here.
I can access a snapshot of Loday's web page on the Internet Archive but it seems that there is no snapshot of the slides of this talk.
I used to have a PDF of these slides, but I can't find it any more. Would anyone here have a copy of them?
I don't have a copy, and I haven't been able to find one by googling. In case it helps, I am guessing the title of the talk was "Algebras, operads, combinads". Google Scholar also provides this description: "Slides of a talk given at HOGT Lille on 23th of March".
Yes, that was the title, thanks :) Hopefully someone has a personal copy. I remember the slides having interesting new ideas and being very readable, it would be a shame if they were lost.
Did you try to contact directly people at Irma to see whether they still have a private archive of the website ?
That would be the logical next step. I couldn't find a general contact email for the IRMA so I sent an email to someone in Loday's old research group. Hopefully the slides turn up. Thanks!
Update: Someone at the IRMA told me that the Wayback Machine has a snapshot of Loday's website here that includes the PDF of the slides.
The difference was between "irma-web1.math.unistra.fr" and "irma.math.unistra.fr"
