We use super qq-Howe duality to provide diagrammatic presentations of an idempotented form of the Hecke algebra and of categories of glN\mathfrak{gl}_N-modules (and, more generally, glNM\mathfrak{gl}_{N|M}-modules) whose objects are tensor generated by exterior and symmetric powers of the vector representations. As an ap…

Khovanov and Rozansky's categorification of the HOMFLY-PT polynomial is invariant under braidlike isotopies for any link diagram and Markov moves for braid closures. To define HOMFLY-PT homology, they required a link to be presented as a braid closure, because they did not prove invariance under the other oriented Reid…

This work challenges the assumption that shorter conformal prediction intervals are always better.

problem The conventional evaluation of conformal prediction metrics (coverage and interval length) may not fully capture the quality of predictions.
method The Prejudicial Trick (PT) is introduced, which probabilistically returns either a null interval or a longer one to maintain valid coverage while potentially reducing interval length.
result The Prejudicial Trick can yield deceptively shorter intervals without compromising coverage, but introduces practical vulnerabilities.

We then define reduced colored HOMFLY-PT homologies and prove that they arise as large N limits of sl(N) homologies. Together, these results allow proofs of many aspects of the phys…
