Use plural or singular first person in abstract of a talk on collaborative work? When writing an abstract for a talk on a topic that I have collaborated on with others, should I be using the plural form, such as 


  "We have shown this and that ..." 


or is it better to write it as:


  "I will discuss this and that ..."
Use "we", because although only one person will be giving the talk, you are representing the work of multiple people.
