Matrix Schubert varieties are affine varieties that arise in the study of the complete flag varieties. They are the orbit closures of permutation matrices under B_{-}*B action and are the vanishing sets of the Schubert determinantal ideals. We gave a minimal list of equations that define matrix Schubert varieties along with some implications. This is based on joint work with Alexander Yong.
