Question

Can I use on instead of ''about'' in these exemples?
E.g.1: A lecture on economics (Is ''A lecture about economics'' possible in this case?) 
E.g.2: We are talking about business, would you to like to enjoy with us? (Can I use ''on'' instead of ''about'' in this case?)

Answer

Hello Stephan,
In the first example, both are interchangable and correct.
'A lecture on economics' is correct
'A lecture about economics' is correct

In the second example, only the first sentence is correct.
'We are talking about business' is correct
'We are talking on business' is incorrect

You could use... we are talking on the subject of business.

Hope that helps,
Wade.

Answer

1) Yes, you can use either "about" or "on" here. "On" sounds more natural to me here, but that might just be me.

2) No, you can only use "about" here. "...enjoy with us" should also be "join us".
