Exceptional Riemann-Roch Theorems
For a smooth projective variety, the classical Hirzebruch--Riemann--Roch (HRR) theorem asserts the isomorphism between the Chow ring and the Grothendieck K-ring of vector bundles over rational coefficients. For certain toric varieties, we show an integral isomorphism between the two rings, different from the classical HRR, and discuss its utility in combinatorial contexts. Joint works with Andrew Berget, Alex Fink, June Huh, Hunter Spink, Dennis Tseng.
