Harbingers of Artin's Reciprocity Law. I. The Continuing Story of Auxiliary Primes

- Mathematics
- 2011

In this article we present the history of auxiliary primes used in proofs of reciprocity laws from the quadratic to Artin's reciprocity law. We also show that the gap in Legendre's proof can be… Expand

The theory is an attempt to generalize the results of the classical class field theory to arbitrary normal fields using the theory of p-primary factor sets, that is, factor sets whose elements involve only the divisors of a fixed prime divisor p of k. Expand

A correction to Hasse's version of the Grunwald–Hasse–Wang theorem

- Mathematics

While reading Hasse’s paper on the Grunwald theorem [5], I recently discovered a slight error in the statement and proof of two of Hasse’s theorems. These two theorems, the ‘‘Schwacher… Expand

A Note on Regular Crossed Products and Galois Representations

A crossed product representing an associative finite dimensional central simple algebra over a field is called regular if all values of the corresponding cocycle are roots of unity. Under a certain… Expand
