K-polynomials of multiplicity-free varieties

Federico Castillo, Yairon Cid-Ruiz, Fatemeh Mohammadi +1

We describe the twisted $K$ -polynomial of multiplicity-free varieties in a multiprojective setting. More precisely, for multiplicity-free varieties, we show that the support of the…

When are multidegrees positive?

Federico Castillo, Yairon Cid-Ruiz, Binglin Li +2

Let $k$ be an arbitrary field, $P = P_{k}^{m_{1}} \times_{k} \dots \times_{k} P_{k}^{m_{p}}$ be a multiprojective space over $k$ , and $X \subseteq P$ be a closed subscheme of $P$ . We provide…

Representable Chow classes of a product of projective spaces

Federico Castillo, Binglin Li, Naizhen Zhang

Inside a product of projective spaces, we try to understand which Chow classes come from irreducible subvarieties. The answer is closely related to the theory of integer polymatroi…
