Abstract:
We prove some general results about the Iwasawa invariants ${\lambda ^ - }$ and ${\mu ^ - }$ of the 4pth cyclotomic field (p an odd prime), and determine the values of these invariants for $p < {10^4}$. The properties of ${\lambda ^ - }$ and ${\mu ^ - }$ are closely connected with the E-irregularity (i.e. the irregularity with respect to the Euler numbers) of p. A list of all E-irregular primes less than ${10^4}$, computed by the first author, is included and analyzed.References
