Introduction to Equivariant Cohomology in Algebraic Geometry (IMPANGA 2010)
Dave Anderson
These are lecture notes from the IMPANGA 2010 Summer School. The lectures survey some of the main features of equivariant cohomology at an introductory level. The first part is an…

Positivity of equivariant Gromov-Witten invariants
Dave Anderson, Linda Chen
We show that the equivariant Gromov-Witten invariants of a projective homogeneous space G/P exhibit Graham-positivity: when expressed as polynomials in the positive roots, they hav…

Equivariant quantum Schubert polynomials
Dave Anderson, Linda Chen
We establish an equivariant quantum Giambelli formula for partial flag varieties. The answer is given in terms of a specialization of universal double Schubert polynomials. Along t…
