    Frobenius singularities of permanental varieties. .
    A permanent of a square matrix is exactly its determinant with all minus signs becoming plus. Despite the similarities, the computation of a determinant can be done in polynomial time, while that of a permanent is an NP-hard problem. In 2002, Laubenbacher and Swanson defined $P_t(X)$ to be the ideal generated by all t-by-t subpermanents of $X$, and called it a permanental ideal. This is a counterpart of determinantal ideals, the center of many areas in Algebra and Geometry. We will discuss properties of $P_2(X)$, including their Frobenius singularities over a field of prime characteristic, and related open questions.
