Projective Dimension of String and Cycle Hypergraphs
Kuei-Nuan Lin, Paolo Mantero
We present a closed formula and a simple algorithmic procedure to compute the projective dimension of square-free monomial ideals associated to string or cycle hypergraphs. As an a…

Normal 0-1 polytopes
Huy Tai Ha, Kuei-Nuan Lin
We study the question of when 0-1 polytopes are normal or, equivalently, having the integer decomposition property. In particular, we shall associate to each 0-1 polytope a labeled…

Rees Algebras of Truncations of Complete Intersections
Kuei-Nuan Lin, Claudia Polini
In this paper we describe the defining equations of the Rees algebra and the special fiber ring of a truncation I of a complete intersection ideal in a polynomial ring over a field…
