Let k be a real abelian number field and p an odd prime. We give a criterion for the vanishing of the \*-invariant for the Z p -extension of k and apply it to give some examples of \*=0.

β¦ Synopsis
Let p be an odd regular prime number. We prove that there exist infinitely many totally real number fields k of degree p&1 whose class numbers are not divisible by p. Moreover, for certain regular prime number p, we prove that there exist infinitely many totally real number fields k of degree p&1 whose Iwasawa * p -, + p -invariants vanish.

For a prime number p, let β«ήβ¬ p be the finite field of cardinality p and X Ο X p a fixed indeterminate. We prove that for any natural number N, there exist infinitely many pairs ( p, K/β«ήβ¬ p (X )) of a prime number p and a ''real'' quadratic extension K/β«ήβ¬ p (X ) for which the genus of K is one and
Let k be a real abelian number field with Galois group 2 and p an odd prime number. Denote by k the cyclotomic Z p -extension of k with Galois group 1 and by k n the nth layer of k Γk. Assume that the order of 2 is prime to p and that p splits completely in kΓQ. In this article, we describe the orde
Suppose g > 2 is an odd integer. For real number X > 2, define S g Γ°X Γ the number of squarefree integers d4X with the class number of the real quadratic field QΓ° ffiffiffi d p Γ being divisible by g. By constructing the discriminants based on the work of Yamamoto, we prove that a lower bound S g Γ°X
In this paper we develop two ways of computing special values of zeta function attached to a real quadratic field. Comparing these values we obtain various class number 1 criteria for real quadratic fields of Richaud Degert type.
