Quantized integral models of reductive monoids
Jingren Chi, Simon Jacques
We construct quantized integral models of reductive monoids and establish their finite-generation properties. We also describe the quantized coordinate rings of the basic affine sp…

Reductive monoids over general base
Jingren Chi, Simon Jacques
We develop a theory of affine algebraic monoids over connected base schemes whose unit groups are split reductive groups. Our main result is a classification theorem for such objec…
