Ordered Set Partitions, Generalized Coinvariant Algebras, and the Delta Conjecture

Abstract: I will discuss the use of orbit harmonics in constructing coinvariant-type algebras related to the Delta Theorem, Hall-Littlewood polynomials, and more. Time permitting, I'll also discuss some varieties whose cohomology rings are presented by these algebras.
