Abstract
We outline some model-building procedures for infinitary Gödel logics, including a suitable ultrapower construction. As an application, we provide two proofs of the fact that the usual characterizations of cardinals \(\kappa \) such that the Compactness and Weak Compactness Theorems hold for the infinitary language \(\mathcal {L}_{\kappa , \kappa }\) are also valid for the corresponding Gödel logics.

Notes
- 1.
Recall that a (proper) filter \(U\ne \wp (X)\) on a set X is a collection of subsets of X that is closed under binary intersections and supersets.
- 2.
As unfortunate as it is, ‘V’ is the usual notation for this.
