An Odd-Divisor Obstruction for Cyclically Invariant Grassmannian Initial Ideals
Over a field of characteristic zero, we prove that the Pluecker ideal of Gr(k,n) has no monomial initial ideal invariant under cyclic rotation whenever gcd(k,n) has an odd divisor greater than one. More generally, for n=mq and k=rq with q>1 odd and 1<=r
