“(Weak) Konig’s Lemma over RCA0.”

We investigate the addition of Konig’s Lemma to RCA0. In doing so, we will examine the power of RCA0 in more detail, culminating in a proof that the Lemma is equivalent to ACA0 when working over RCA0. Time permitting, we begin a discussion of using Weak Konig’s Lemma in the same situation.
