Abstract
For a partition of , the _Specht ideal_ is the ideal generated by all Specht polynomials of shape . In their unpublished manuscript, Haiman and Woo showed that is a radical ideal, and gave its universal Gr\"obner bases (recently, Murai et al. published a quick proof of this result). On the other hand, an old paper of Li and Li studied analogous ideals, while their ideals are not always radical. In the present paper, we introduce a class of ideals which generalizes both Specht ideals and _radical_ Li-Li ideals, and study their radicalness and Gr\"obner bases.
