The Inverse Galois problem remains a fascinating yet unanswered question. The standard approach through algebraic geometry is to construct a Galois branched covering of the projective line over the rationals with a desired group G. Then one invokes the Hilbert Irreducibility Theorem to construct a G

Abstract
Let L/F be a dihedral extension of degree 2__p__, where p is an odd prime. Let K/F and k/F be subextensions of L/F with degrees p and 2, respectively. Then we will study relations between the pβranks of the class groups Cl(K) and Cl(k). (Β© 2005 WILEYβVCH Verlag GmbH & Co. KGaA, Weinheim)

## IN MEMORIAM MARY GLAZMAN We shall show that the Hecke order H H of the dihedral group of order 2 ΠΈ p n D n w y1 x over β«ήβ¬ q, q for an odd prime p is a projectively cellular order. We describe the corresponding cell ideals and compute the extension groups between the correw y1 x sponding cell m
We prove that for any primes p 1 ; . . . ; p s there are only finitely many numbers Q s iΒΌ1 p ai i ; a i 2 Z ΓΎ ; which can be orders of dihedral difference sets. We show that, with the possible exception of n ΒΌ 540; 225; there is no difference set of order n with 15n410 6 in any dihedral group.
The reciprocity law of Coleman for the Hilbert norm residue symbol has allowed the computation of the conductors of the abelian Kummer extensions Q p ( p n a, `pn )ΓQ p (`pn ) with a # Q p and `pn a primitive ( p n ) th root of unity for a fixed prime p and all positive integers n. From these conduc
