I thought that access structure and access tree are equivalent but I've read in a paper (page 3) that there are at least three types of access structures :

AND gates
Access tree
LSSS generating matrix

I would like to know what is the difference between them, are they equivalent or some of them are more expressive (better to use) than others?

Thank you in advance.

You haven't yet accepted (or it seems to me even upvoted) any answer to your previous questions. Please revisit them and see if they solve your problem. – Artjom B. Feb 16 '16 at 11:36
