Re: [isabelle] Operations over sets in Isabelle



Hi Bogdan,

as far as I understand, you want to take the product of two sets and
then apply a binary operator on it.  This can be done using the existing
 image (`) and product operators (<*>), e.g.

	(\<lambda>(a, b). a + b) ` (A <*> N)

form the sum of two sets.

Hope this helps,
	Florian
