We consider the statistical experiment given by a sample y(1), . . . , y(n) of a stationary Gaussian process with an unknown smooth spectral density f . Asymptotic equivalence, in the sense of Le Cam’...
THE CHERNOFF LOWER BOUND FOR SYMMETRIC QUANTUM HYPOTHESIS TESTING
CHERNOFF LOWER BOUND SYMMETRIC QUANTUM HYPOTHESIS TESTING

2015/8/25
We consider symmetric hypothesis testing in quantum statistics, where the hypotheses are density operators on a finite-dimensional complex Hilbert space, representing states of a finite quantum system...

We consider the problem of discriminating between two different states of a finite quantum system in the setting of large numbers of copies, and find a closed form expression for the asymptotic expone...

We introduce the groupoidal analogue e to Joyal’s cellular category and we prove that e is a strict test category in the sense of Grothendieck.

2010/12/28
Recent lab experiments by Traulsen et al. [1] for the spatial pris-oner’s dilemma suggest that exploratory behavior of human subjects prevents cooperation through neighborhood interactions over exper-...
Completeness of the Bethe ansatz on Weyl alcoves
Bethe ansatz root systems spectral analysis reflection groups
font style='font-size:12px;'>
2010/12/10
We prove the completeness of the Bethe ansatz eigenfunctions of the Laplacian on a Weyl alcove with repulsive boundary condition at the walls. For the root system of type A this amounts to the result ...
New bounds on the maximum ionization of atoms

font style='font-size:12px;'>
2010/12/6
We prove that the maximum number Nc of non-relativistic electrons that a nucleus of charge Z can bind is less than 1.22Z + 3Z1/3. This improves Lieb’s upper bound Nc < 2Z + 1 [Phys. Rev. A 29, 3018-30...
When can several people simulate a private random oracle for someone else?
private random oracle
font style='font-size:12px;'>
2010/12/16
Many models of secure multiparty computation supply each participant with a private random oracle [Yao82,Sha79,GMW87,Csi08]. If one participant does not have access to a private random oracle, perhaps...
Characterizations of transversal and fundamental transversal matroids
Matroid transversal matroid fundamental transversal matroid
font style='font-size:12px;'>
2010/12/8
A result of Mason, as refined by Ingleton, characterizes transversal matroids as the matroids that satisfy a set of inequalities that relate the ranks of intersections and unions of nonempty sets of c...

Local quasiconvexity Coherence Small-cancellation Relative hyperbolicity
font style='font-size:12px;'>
2010/12/8
Given a group acting cellularly and cocompactly on a simply-connected 2-complex, we provide a criterion establishing that all finitely generated subgroups have quasiconvex orbits. This work generalize...
Challenging the empirical mean and empirical variance: a deviation study
Non-parametric estimation M-estimators PAC-Bayes bounds
font style='font-size:12px;'>
2010/12/3
We present new M-estimators of the mean and variance of real valued random variables, based on PAC-Bayes bounds. We analyze the non-asymptotic minimax properties of the deviations of those estimators ...
