Nesting behind -invariants
Shoma Sugimoto
In the spirit of arXiv:2501.12985, we propose an abelian categorification of -invariants for negative definite plumbed 3-manifolds. It provides a blueprint for the expecte…

Hypercubic structures behind -invariants
Shoma Sugimoto
We propose an abelian categorification of -invariants for Seifert -manifolds. First, we give a recursive combinatorial derivation of these -invariants using gr…
