Original Kurzfassung:
The algebraic geometry of a universal algebra A is defined as the collection of solution sets of systems of term equations. Two algebras are called algebraically equivalent if they have the same algebraic geometry. We prove that on a finite set A with |A| > 3 there are countably many algebraically inequivalent Mal?cev algebras and that on a finite set A with |A| > 2 there are continuously many algebraically inequivalent algebras.
