Abstract

The symmetric gln\mathfrak{gl}_n-homologies, introduced by Robert and Wagner, provide a categorification of the Reshetikhin--Turaev invariants corresponding to symmetric powers of the standard representation of quantum gln\mathfrak{gl}_n. Unlike in the exterior setting, these homologies are already non-trivial when n=1n=1. Moreover, in this case, their construction can be greatly simplified. Our first aim is giving a down-to-earth description of the non-equivariant symmetric gl1\mathfrak{gl}_1-homology, together with relations that hold in this setting. We then find a basis for the state spaces of graphs, and use it to construct an algorithm and a program computing the invariant for uncolored links.
