Lexsegment ideals in polynomial rings

Abstract :

I will discuss about the lexsegment ideals in polynomial rings, particularly in K[x,y]. We will prove that the if $I$ is a lexsegment ideal in K[x,y], then the Rees algebra of $I$ is Cohen-Macaulay if and only if the associated graded ring is Cohen-Macaulay if and only if the fiber cone is Cohen-Macaulay.
