<p class="MsoNormal" style="margin:0cm 0cm 0.0001pt;line-height:normal;font-size:11pt;font-family:"Calibri","sans-serif""><span style="font-family:"Times New Roman","serif"">The Rees algebra $R[It]$ plays an
important role in commutative algebra because it encodes the asymptotic
behavior of the ideal I. An important problem in the theory of Rees algebras is
to determine defining equations of the Rees algebras. More generally, given any
ideals $I_1,\dots,I_r$ in a ring $R$, one would like to describe defining
equations of the multi-Rees algebra $R[I_1t_1,\dots,I_rt_r]$. This is a problem
in pure algebra but when we deal with ideals in a polynomial ring we may use
computational methods to find the equations. In this talk I describe defining
equations of the multi-Rees algebras of certain family of ideals using results
in pure and computational commutative algebra. To do this I start the talk by
discussing some concepts in computational commutative algebra.<span></span></span></p>
