How should I reference my own previous work in a talk to a general audience? I have to give a presentation to a general scientific audience (specifically, an interview talk). As part of the presentation I would like to highlight some of my previous work. 

I work in mathematics, where paper authorship is always alphabetical. The standard practice in talks is to replace your own name with an initial. That is, a person with the last name Potter might present their joint work with Granger and Weasley as "the horcrux theorem, due to Granger-P.-Weasley". 

Presumably this mathematical convention is not used or even known in the general scientific community. 

How do people reference their own work in other fields? How do people reference their own work when talking to people in other fields? To people in a mixed group of many fields? 



ETA: thanks everyone for your answers! 

I’m editing to highlight a point which hasn’t been addressed yet - how does one convey that authorship in mathematics is alphabetical? (My last name begins with R so I’m almost always the last author in any paper of mine.) 

I don’t want to change the order of authors in a published paper, but I also don’t want it to seem like I’ve never been a first author. 

Is it okay to simply state this verbally? This seems like it could be perceived as somewhat tacky....
If the list of authors is short, just write all of them:
For example: Lagrange, Cauchy and Carnot, 1800, Journal of Mathematics
You may want to put your own name in bold.
If there are many authors, then a pretty standard way in many disciplines is to write as FirstName et al., see here: https://www.scribendi.com/advice/how_to_use_et_al.en.html 
But if you are at the middle, you need to choose. Maybe something link:  AAA ... YouName et al., 
Or you can still put your name as first and the rest as et al.,
