Remarks on 2-dimensional HQFT's

Mihai D. Staic, Vladimir Turaev

We introduce and study algebraic structures underlying 2-dimensional Homotopy Quantum Field Theories (HQFTs) with arbitrary target spaces. These algebraic structures are formalized…

Symmetric cohomology of groups in low dimension

Mihai D. Staic

We give an explicit characterization for group extensions that correspond to elements of the symmetric cohomology $H S^{2} (G, A)$ . We also give conditions for the map $HS^n(G,A)\to H^n…

Secondary Cohomology and k-invariants

Mihai D. Staic

For a triple $(G, A, κ)$ (where $G$ is a group, $A$ is a $G$ -module and $κ : G^{3} \to A$ is a 3-cocycle) and a $G$ -module $B$ we introduce a new cohomology theory $_{2} H^{n} (G, A, κ; B)$ which…

A quotient of the braid group related to pseudosymmetric braided categories

Florin Panaite, Mihai D. Staic

Motivated by the recently introduced concept of a pseudosymmetric braided monoidal category, we define the pseudosymmetric group PS_n, as the quotient of the braid group B_n by the…
