The enhanced principal rank characteristic sequence for skewsymmetric matrices
Fallat, Shaun; Olesky, Dale; van den Driessche, Pauline
The enhanced principal rank characteristic sequence (eprsequence) was originally defined for an n ×n real symmetric matrix or an n ×n Hermitian matrix. Such a sequence is defined to be l1l2···ln where lk is A,S, or N depending on whether all, some, or none of the matrix principal minors of order k are nonzero. Here we give a complete characterization of the attainable eprsequences for real skewsymmetric matrices. With the constraint that lk=0 if k is odd, we show that nearly all eprsequences are attainable by skewsymmetric matrices, which is in contrast to the case of real symmetric or Hermitian matrices for which many eprsequences are forbidden.
