Table 2 lists E n(x) for n ≤ 10, along with its factorization into irreducibles and the Coxeter number h n. Here Φ k(x) is the cyclotomic polynomial for the primitive kth roots of unity. The spherical and affine cases. Since E WebLeopoldt concentrated on a fixed cyclotomic field, and established various p-adic analogues of the classical complex analytic class number formulas. In particular, this led him to introduce, with Kubota, p-adic analogues of the complex L-functions attached to cyclotomic extensions of the rationals.
