Period of the Ikeda-Miyawaki lift

Tomoyoshi Ibukiyama, Hidenori Katsurada, Hisashi Kojima

In this paper, first we give a weak version of Ikeda's conjecture on the period of the Ikeda-Miyawaki lift. Next, we confirm this conjecture rigorously in some cases.

Harder's conjecture II

Hiraku Atobe, Masataka Chida, Tomoyoshi Ibukiyama +2

Let $f$ be a primitive form of weight $2 k + j - 2$ for $S L_{2} (Z)$ , and let $P$ be a prime ideal of the Hecke field of $f$ . We denote by $S p_{m} (Z)$ the Siegel modular group of degree $m$ .…

Genus character $L$ -functions of quadratic orders in an adelic way and maximal orders of matrix algebras

Tomoyoshi Ibukiyama

For a quadratic extension $K$ of $Q$ , we consider orders $O$ in $K$ that are not necessarily maximal and the ideal class group $C l^{+} (O)$ in the narrow sense of proper ide…
