On higher regulators of Siegel threefolds II: the connection to the special value
Published online by Cambridge University Press: 27 March 2017
Abstract
We establish a connection between motivic cohomology classes over the Siegel threefold and non-critical special values of the degree-four $L$-function of some cuspidal automorphic representations of
$\text{GSp}(4)$. Our computation relies on our previous work [On higher regulators of Siegel threefolds I: the vanishing on the boundary, Asian J. Math. 19 (2015), 83–120] and on an integral representation of the
$L$-function due to Piatetski-Shapiro.
