Dear Mathforum,  

I am giving a job talk in the next couple of weeks and I am still struggling 
to come up with a suitable talk.  
I graduated in september of 2010 and so I have been a post doc for a year and a bit.  I am giving the talk at a "private, nonsectarian research university"  which has roughly 25-30 faculty.   I have between 5 and 10 papers on roughly 3 topics.  

I was told the talk will be a colloquim style talk and not a specialized analysis and pde talk which is my area.  Also I will not be giving a seperate specialized talk.     
 

I am really struggling with what is the correct format I should use for my talk.  In any case I will be using Beamer.   

My question is should I: 

1)  pick one of my topic areas and then go through some background and then list my results (maybe giving a word or two about why they are not totally trivial)

or 

2)  Should I pick one small result and try and give a somewhat detailed account 

or ???   (I have seen both done in the colloquim portion of a job talk).  


Any comments would be greatly appreciated.  

Thanks
David
