Abstract

 

In this thesis, we study t-spread strongly stable monomial ideals. It is proved that for an ideal to be t-spread strongly stable, it is sufficient for the definition criterion to be satisfied only on its minimal monomial generating set. The generators, height, Cohen-Macaulayness, and minimal free resolution of some special classes of t-spread strongly stable monomial ideals, namely,

t-spread Veronese ideals and t-spread principal Borel ideals and their Alexander dual are studied. We also study the Rees algebras of t-spread principal Borel ideals, and it is shown that they have the so-called l-exchange property. Consequently, the Rees algebra of a t-spread principal Borel ideal is Koszul.
