WebDefinition 10.122.3. Let R \to S be a finite type ring map. Let \mathfrak q \subset S be a prime. If the equivalent conditions of Lemma 10.122.2 are satisfied then we say R \to S is quasi-finite at \mathfrak q. We say a ring map A \to B is quasi-finite if it is of finite type and quasi-finite at all primes of B. The theory of finite fields is perhaps the most important aspect of finite ring theory due to its intimate connections with algebraic geometry, Galois theory and number theory.

"Webtities of a finite-ring are finitely based; the arithmetical ring case is shown by H. Werner and R. Wille [13]. From [6], it also follows that a finite ring generates a variety containing only finitely many subvarieties. We show here that the converse is also true.
