Invertible sheaves and -invertible sheaves on the isomeric supergrassmannian and its toric subvarieties
Eric Jankowski
We provide an elementary proof that with the exceptions of certain -projective spaces, both the Picard group and the -Picard set of the isomeric (i.e. type-Q) supergrassmanni…

Reduced superschemes and the combinatorics of toric supervarieties
Eric Jankowski
We propose new definitions of integral, reduced, and normal superrings and superschemes to properly establish the notion of a supervariety. We generalize several results about clas…
