NettetTheorem 2 shows that the Legendre transform of a convex function is itself convex. The following lemma states that if a proper convex function is lower semicontinuous, then its Legendre transform is proper; one proves the lemma using the Hahn-Banach separation theorem.1 We use this lemma in the proof of the theorem that comes after. Lemma 3.

NettetThis is fair since Legendre's proof of quadratic reciprocity was unsatisfactory, while he offered no proof of the theorem on primes in an arithmetic progression.
