Title: Integral Closures of Ideals: Example Driven Theory Using CASs, Such As Macaulay2, Singular, and/or Magma
Abstract: I'll talk about my view of integral closures of ideals and an alternative to the Rees algebra of an ideal. We'll do examples, starting with \((x^2,y^2)\), \((x^5,y^5)\), and \((x^5-x^2,y^5-y^2)\), and then \((y^2-zx,zy-x^3,z^2-yx^2)\).
