Talk:Strength (mathematical logic)

Shouldn't that read: "$$\alpha$$ is said to be as strong as a logic $$\beta$$ if every elementary class in $$\beta$$ is an elementary class in $$\alpha$$?" At least that's what the cited reference (Extended logics: the general framework) appears to be stating. — Preceding unsigned comment added by 173.35.108.182 (talk) 02:00, 4 February 2013 (UTC)

Strength vs. Weakness
But this article does not inform when one system is weaker and the other stronger. Can some elaborate, or explain why non is need? — Preceding unsigned comment added by 71.183.110.20 (talk) 17:32, 13 December 2022 (UTC)
