Fluctuation moments induced by conjugation with asymptotically liberating random matrix ensembles [PDF]

arXiv, 2020
G. Anderson and B. Farrel showed that conjugation of constant matrices by asymptotically liberating random unitary matrices give rise to asymptotic free independence. Independent Haar-unitary random matrices and independent Haar-orthogonal random matrices are examples of asymptotically liberating ensembles. In this paper, we investigate the fluctuation

The observation of electron trap liberation in MgF$_{2}$ doped with Yb$^{2+}$ using a two-color excitation experiment [PDF]

, 2011
We utilize the optical transitions of Yb$^{2+}$ excited by an ultraviolet optical parametric amplifier to probe electron trap liberation in MgF$_{2}$ via the observation of a photoluminescence enhancement effect induced by a subsequent infrared pulse from a free-electron laser.

Free floating planets in stellar clusters? [PDF]

Mon.Not.Roy.Astron.Soc. 322 (2001) L1, 2001
We have simulated encounters between planetary systems and single stars in various clustered environments. This allows us to estimate the fraction of systems liberated, the velocity distribution of the liberated planets, and the separation and eccentricity distributions of the surviving bound systems.

The algebraic structure of quantum partial isometries [PDF]

Infin. Dimens. Anal. Quantum Probab. Relat. Top. 19 (2016), 1-36, 2014
The partial isometries of $\mathbb R^N,\mathbb C^N$ form compact semigroups $\widetilde{O}_N,\widetilde{U}_N$. We discuss here the liberation question for these semigroups, and for their discrete versions $\widetilde{H}_N,\widetilde{K}_N$. Our main results concern the construction of half-liberations $\widetilde{H}_N^\times,\widetilde{K}_N^\times ...

Two Forms of One Useful Logic: Existential Fixed Point Logic and Liberal Datalog [PDF]

arXiv, 2008
A natural liberalization of Datalog is used in the Distributed Knowledge Authorization Language (DKAL). We show that the expressive power of this liberal Datalog is that of existential fixed-point logic. The exposition is self-contained.

Comparing Weakest Precondition and Weakest Liberal Precondition [PDF]

arXiv, 2015
In this article we investigate the relationships between the classical notions of weakest precondition and weakest liberal precondition, and provide several results, namely that in general, weakest liberal precondition is neither stronger nor weaker than weakest precondition, however, given a deterministic and terminating sequential while program and a

Half-liberated real spheres and their subspaces [PDF]

arXiv, 2015
We describe the quantum subspaces of Banica-Goswami's half-liberated real-spheres, showing in particular that there is a bijection between the symmetric ones and the conjugation stable closed subspaces of the complex projective spaces.

The failure of liberalism and liberal education [PDF]

Educational Philosophy and Theory, 2019
Anyone living in the US in the 1970s might be forgiven for thinking that ‘this is as good as it gets’, that we are living the good life, and that we can continue to expect incremental improvements ...

Liberation theory for noncommutative homogeneous spaces [PDF]

Ann. Fac. Sci. Toulouse Math. 26 (2017), 127-156, 2015
We discuss the liberation question, in the homogeneous space setting. Our first series of results concerns the axiomatization and classification of the families of compact quantum groups $G=(G_N)$ which are "uniform", in a suitable sense. We study then the quotient spaces of type $X=(G_M\times G_N)/(G_L\times G_{M-L}\times G_{N-L})$, and the liberation

A note on the half-liberation operation [PDF]

arXiv, 2019
We propose a new approach to the half-liberation question, for the compact groups $T_N\subset G_N\subset U_N$, where $T_N=\mathbb Z_2^N$. Indeed, we can construct a quantum group $T_N^*\subset G_N^*\subset U_N^*$, simply by setting $G_N^*=$.
