Initial layer of the anti-cyclotomic $Z_{3}$ -extension of $Q (- m)$ and capitulation phenomenon

Georges Gras

Let $k = Q (- m)$ be an imaginary quadratic field. We consider the properties of capitulation of the $p$ -class group of $k$ in the anti-cyclotomic $Z_{p}$ -extens…

On the $Z_{p}$ -extensions of a totally $p$ -adic imaginary quadratic field -- With an appendix by Jean-François Jaulent

Georges Gras

Let $k = Q (- m)$ and $p \geq 3$ split in $k$ . We prove new properties of the $Z_{p}$ -extensions $K / k$ , distinct from the cyclotomic one; we do not assume $K/…

Genus theory of p-adic pseudo-measures -- Tame kernels and abelian p-ramification

Georges Gras

We consider, for real abelian fields K, the Birch--Tate formula linking the tame kernel \#K\_2(Z\_K) to $ζ$ \_K(-1); we compare, for quadratic and cyclic cubic fields with p=2,3, \#…
