[edit] Abstract algebraic systems

An Abstract Algebraic System is a tuple of the form . In this is a set, f_is are function symbols of some arity , R_is are predicate symbols of some arity and ν is an interpretation of these symbols on the set.

If no predicate symbols are present then S is an Algebra (or a Universal Algebra). We allow 0-ary operations in the above, so distinguished elements must be interpreted as 0-ary operations.
