Thank you all for your comments!

As I am dealing with symbols, I expect nothing else:  a==0 means it 
should be zero (which is a real number), a>0 means it should be greater 
than zero (which implies that it should be real), so the assumptions are 
already there.

Simplify (or Reduce, or Resolve...) does the job.
