Kruskal-Katona theorem for t-spread strongly stable ideals
We prove that any t-spread strongly stable ideal has a unique t-spread lex ideal with the same ft -vector. We also characterize the possible ft -vectors of t-spread strongly stable ideals in the ”t-spread” analogue of Kruskal-Katona theorem.
