Query: On the mod $p$ kernel of the theta operator and Eisenstein series   Siegel modular forms in the space of the mod $p$ kernel of the theta operator
are constructed by the Eisenstein series in some odd-degree cases.
Additionally, a similar result in the case of Hermitian modular forms is given.
