Transfer of Unitary Representations [PDF]
Introduction. This paper has as its primary purpose a clear exposition of the idea in [21] which we describe as transfer between real forms of a semi-simple Lie group over C. The basic point is that there are representations of one real form that can be more easily understood in the context of another real from.

The conjugacy relation on unitary representations [PDF]
We show that the unitary conjugacy relation for unitary representations of a second countable locally compact group on a separable Hilbert space is a Borel equivalence relation.

On Constructing Informationally Complete Covariant Positive Operator-Valued Measures
We study a projective unitary representation of the product G=G˜×G, where G is a locally compact Abelian group and G^ is its dual consisting of characters on G.

Representation and design of wavelets using unitary circuits [PDF]
The representation of discrete, compact wavelet transformations (WTs) as circuits of local unitary gates is discussed. We employ a similar formalism as used in the multiscale representation of quantum many-body wave functions using unitary circuits ...

Homotopy representations of the unitary groups [PDF]
Let $G$ be a compact connected Lie group and let $ , $ be complex vector bundles over the classifying space $BG$. The problem we consider is whether $ $ contains a subbundle which is isomorphic to $ $. The necessary condition is that for every prime $p$ the restriction $ |_{BN_p^G}$, where $N_p^G$ is a maximal $p$-toral subgroup of $G$, contains a

A note on cocycles of unitary representations [PDF]
Given a unitary representation U U of a locally compact abelian group G G , we investigate the relationship between two cocycles a 1 , a 2 : V a 1

Covariant catalysis requires correlations and good quantum reference frames degrade little [PDF]
Catalysts are quantum systems that open up dynamical pathways between quantum states which are otherwise inaccessible under a given set of operational restrictions while, at the same time, they do not change their quantum state.

Hamiltonian Quantization of Chern-Simons theory with SL(2,C) Group [PDF]
We analyze the hamiltonian quantization of Chern-Simons theory associated to the universal covering of the Lorentz group SO(3,1). The algebra of observables is generated by finite dimensional spin networks drawn on a punctured topological surface.

On cospectrality of gain graphs
We define GG-cospectrality of two GG-gain graphs (Γ,ψ)\left(\Gamma ,\psi ) and (Γ′,ψ′)\left(\Gamma ^{\prime} ,\psi ^{\prime} ), proving that it is a switching isomorphism invariant.
