The Class Number Formulas in Quadratic and Cyclotomic Function Fields

  • Michael Rosen
Part of the Graduate Texts in Mathematics book series (GTM, volume 210)


In this chapter we will discuss the analogues of some fascinating class number formulas which are well known in the case of quadratic and cyclotomic number fields. Some of these go back to the nineteenth century, e.g., the work of Dirichlet and Kummer. More recent contributions are associated with the names of Carlitz, Iwasawa, and Sinnott. We will review some of these results and then formulate and prove a number of analogues in the function field context.
