Open questions for operators related to rectangular Catalan combinatorics
Pages: 673 – 703
We formulate many open questions, most ot them new, regarding Schur positivity, Schur inclusion, $e$-positivity, and $e$-inclusion of interesting symmetric functions arising from operators in the elliptic Hall algebra, and give supporting evidence for why one should expect such behavior. This ties in with many recent advances in the study of Rectangular Catalan Combinatorics and other subjects pertaining to Algebraic Geometry, Representation Theory, and the Homology of Torus Knots.
