+ .. method:: asinequalities()
+
+ Express the polyhedron using inequalities, given as a list of expressions greater or equal to 0.
+
.. method:: widen(polyhedron)

The following functions combine :class:`Polyhedron` or :class:`Domain` instances using logic operators:
-.. function:: Or(domain1, domain2[, ...])
-
- Create the union domain of the domains given in arguments.
-
.. function:: And(domain1, domain2[, ...])
Create the intersection domain of the domains given in arguments.
+.. function:: Or(domain1, domain2[, ...])
+
+ Create the union domain of the domains given in arguments.
+
.. function:: Not(domain)
Create the complementary domain of the domain given in argument.
