Chen-Khovanov spectra for tangles

Geometric Topology 2025-07-08 v2 Algebraic Topology Quantum Algebra

Abstract

We note that our stable homotopy refinements of Khovanov's arc algebras and tangle invariants induce refinements of Chen-Khovanov and Stroppel's platform algebras and tangle invariants, and discuss the topological Hochschild homology of these refinements.
