SUMMARY:Bott’s residue formula in A1-enumerative geometry - Sabrina Paul

DESCRIPTION:In their celebrated work Ellingsrud and Str&oslash\;mme used B
 ott&rsquo\;s residue formula to count the number of twisted cubics on a co
 mplete intersection variety. Recently\, Marc Levine found a quadratic vers
 ion of Bott&rsquo\;s residue formula. In the talk I will recall both the c
 lassical and the quadratic version and explain how one can use it to attac
 k problems in A1-enumerative geometry. If time permits\, I will present jo
 int work with Marc Levine\, namely a quadratic enrichment of Ellingsrud an
 d Str&oslash\;mme&rsquo\;s count of twisted cubics.
