title = "Singular TQFTs, foams and type D arc algebras",
abstract = "We combinatorially describe the 2-category of singular cobordisms, called (rank one) foams, which governs the functorial versionof Khovanov homology. As an application we topologically realizethe type D arc algebra using this singular cobordism construction.",
