We create Resthetikhin-Turaev topological invariants of closed orientable three-manifolds from the quantum supergroup U_q(osp(1|2n)) at certain even roots of unity. To construct the invariants we develop tensor product theorems for finite dimensional modules of U_q(osp(1|2n)) at roots of unity.

Let LL be a link and ΦLA(q)Φ^{A}_{L}(q) its link invariant associated with the vector representation of the quantum (super)algebra Uq(A)U_{q}(A).

Constructs 3D topological field theories from a specific quantum group, linking to physics invariants.

Based on earlier work of the latter two named authors on the higher super-Teichmueller space with N=1\mathcal{N}=1, a component of the flat OSp(12)OSp(1|2) connections on a punctured surface, here we extend to the case N=2\mathcal{N}=2 of flat OSp(22)OSp(2|2) connections. Indeed, we construct here coordinates on the higher super-T…

Let λ:G~Gλ: \tilde{G}\to G be the non-trivial double covering of the symplectic group G=Sp(V,ω)G=Sp(V,ω) of the symplectic vector space (V,ω)(V,ω) by the metaplectic group G~=Mp(V,ω).\tilde{G}=Mp(V,ω). In this case, λλ is also a representation of G~\tilde{G} on the vector space VV and thus, it gives rise to the representation of $\tilde{G…

Matrix formulas for super Teichmüller spaces generalize previous work and yield super λ-lengths.

method Using holonomy matrices of elements in the supergroup OSp(1|2) to compute super λ-lengths in decorated super Teichmüller spaces.
result Matrix formulas for arcs on bordered surfaces yield super λ-lengths in Penner-Zeitlin's decorated super Teichmüller space.

We investigate the concept of equivariant quantization over the superspace R^{p+q|2r}, with respect to the orthosymplectic algebra osp(p+1,q+1|2r). Our methods and results vary upon the superdimension p+q-2r. When the superdimension is nonzero, we manage to obtain a result which is similar to the classical theorem of D…

We present supersymmetric, curved space, quantum mechanical models based on deformations of a parabolic subalgebra of osp(2p+2|Q). The dynamics are governed by a spinning particle action whose internal coordinates are Lorentz vectors labeled by the fundamental representation of osp(2p|Q). The states of the theory are t…

A new method for selective classification trades off accuracy for coverage.

problem Selective classification allows a classifier to abstain from predicting some instances.
method Optimizes a collection of class-wise decoupled one-sided empirical risks.
result The method achieves near-optimal coverage in high target accuracy regimes.

Possible irreducible holonomy algebras $\g\subset\osp(p,q|2m)$ of Riemannian supermanifolds under the assumption that $\g$ is a direct sum of simple Lie superalgebras of classical type and possibly of a one-dimensional center are classified. This generalizes the classical result of Marcel Berger about the classificatio…

We introduce coordinates for a principal bundle ST~(F)S\tilde T(F) over the super Teichmueller space ST(F)ST(F) of a surface FF with s1s\geq 1 punctures that extend the lambda length coordinates on the decorated bundle T~(F)=T(F)×R+s\tilde T(F)=T(F)\times {\mathbb R}_+^s over the usual Teichmueller space T(F)T(F). In effect, the action of…

Extending previous work that involved D3-branes ending on a fivebrane with θYM0θ_{\mathrm{YM}}\not=0, we consider a similar two-sided problem. This construction, in case the fivebrane is of NS type, is associated to the three-dimensional Chern-Simons theory of a supergroup U(mn)(m|n) or OSp(m2n)(m|2n) rather than an ordinary …

We study how to generate new Lie algebras G(N0,...,Np,...,Nn)\mathcal{G}(N_0,..., N_p,...,N_n) from a given one G\mathcal{G}. The (order by order) method consists in expanding its Maurer-Cartan one-forms in powers of a real parameter λλ which rescales the coordinates of the Lie (super)group GG, gipλpgipg^{i_p} \to λ^p g^{i_p}, in a way su…

We extend our previous analysis of Riemannian four-manifolds M admitting rigid supersymmetry to N=1 theories that do not possess a U(1)_R symmetry. With one exception, we find that M must be a Hermitian manifold. However, the presence of supersymmetry imposes additional restrictions. For instance, a supercharge that sq…

The complex Lie superalgebras g\mathfrak{g} of type D(2,1;a)D(2,1;a) - also denoted by osp(4,2;a)\mathfrak{osp}(4,2;a) - are usually considered for "non-singular" values of the parameter aa, for which they are simple. In this paper we introduce five suitable integral forms of g\mathfrak{g}, that are well-defined at singular valu…
