# Corey Harris (UiO): Segre class computation and practical applications

**Abstract: Segre classes are a fundamental notion in algebraic geometry, but they are unfortunately difficult to compute. Fix an ambient smooth projective toric variety T, and consider a subscheme X of a variety Y in T. In this talk I’ll explain how to compute the Segre class of X in Y, pushed forward to T. Such computations can be used to address basic problems like ideal containment (avoiding Gröbner bases). This is joint work with Martin Helmer.**
