Monoidal 2-categories from foam evaluation
Leon J. Goertz, Laura Marino, Paul Wedrich
In this paper we describe a general framework for constructing examples of locally linear semistrict monoidal 2-categories covering many examples appearing in link homology theory.…

A note on TQFTs for orientable 2-dimensional cobordisms
Leon J. Goertz, Paul Wedrich
Topological quantum field theories (TQFTs) are symmetric monoidal functors out of cobordism categories. In dimension two, oriented TQFTs are famously classified by commutative Frob…

A construction of surface skein TQFTs and their extension to 4-dimensional 2-handlebodies
Leon J. Goertz
For a commutative Frobenius algebra , we construct a -dimensional TQFT that assigns to a 3-manifold a skein module of embedded -decorate…
