Sufficiency in quantum statistical inference
Anna Jencova, Denes Petz
This paper attempts to develop a theory of sufficiency in the setting of non-commutative algebras parallel to the ideas in classical mathematical statistics. Sufficiency of a coars…
A quantum homogeneous space of nilpotent matrices
M. Domokos
A quantum deformation of the adjoint action of the special linear group on the variety of nilpotent matrices is introduced. New non-embedded quantum homogeneous spaces are obtained…
On a multivariate version of Bernstein's inequality
P. Major
We prove a multivariate version of Bernstein's inequality about the probability that degenerate -statistics take a value larger than some number . This is an improvement of f…
An exotic smooth structure on CP^2+6CP^2-bar
Andras I Stipsicz, Zoltan Szabo
We construct smooth 4-manifolds homeomorphic but not diffeomorphic to CP^2+6CP^2-bar.
Equilibrium states and their entropy densities in gauge-invariant C*-systems
N. Akiho, F. Hiai, D. Petz
A gauge-invariant C*-system is obtained as the fixed point subalgebra of the infinite tensor product of full matrix algebras under the tensor product unitary action of a compact gr…
The cobordism class of the multiple points of immersions
Gábor Braun
Let f: M -> N be an even codimensional immersion between smooth manifolds. We derive an explicit formula for the Pontrjagin numbers and signature of the multiple point manifolds in…
Largest family without A union B contained in C intersect D
Annalisa De Bonis, Gyula O. H. Katona, Konrad J. Swanepoel
Let F be a family of subsets of an n-element set not containing four distinct members such that A union B is contained in C intersect D. It is proved that the maximum size of F und…
Local chromatic number, Ky Fan's theorem, and circular colorings
Gabor Simonyi, Gabor Tardos
The local chromatic number of a graph was introduced by Erdos et al. in 1986. It is in between the chromatic and fractional chromatic numbers. This motivates the study of the local…
The efficiency of the estimators of the parameters in GARCH processes
István Berkes, Lajos Horváth
We propose a class of estimators for the parameters of a GARCH(p,q) sequence. We show that our estimators are consistent and asymptotically normal under mild conditions. The quasi-…
Counting primes, groups and manifolds
D. Goldfeld, A. Lubotzky, N. Nikolov +1
Let be the modular group and let be the number of congruence subgroups of of index at most . We prove that $\lim\limits_{n\to \infty} \fr…
Cardinal sequences and Cohen real extensions
István Juhász, Saharon Shelah, Lajos Soukup +1
We show that if we add any number of Cohen reals to the ground model then, in the generic extension, a locally compact scattered space has at most (2^{aleph_0})^V many levels of si…
Ozsvath-Szabo invariants and tight contact three-manifolds, I
Paolo Lisca, Andras I Stipsicz
Let S^3_r(K) be the oriented 3--manifold obtained by rational r-surgery on a knot K in S^3. Using the contact Ozsvath-Szabo invariants we prove, for a class of knots K containing a…
Hydrodynamic limit for perturbation of a hyperbolic equilibrium point in two-component systems
Benedek Valko
We consider one-dimensional, locally finite interacting particle systems with two conservation laws. The models have a family of stationary measures with product structure and we a…
Maximal local time of a d-dimensional simple random walk on subsets
Endre Csáki, Antónia Földes, Pál Révész
Strong theorems are given for the maximal local time on balls and subspaces for the -dimensional simple symmetric random walk.
On Vervaat and Vervaat-error type processes for partial sums and renewals
Endre Csáki, Miklós Csörgő, Zdzisław Rychlik +1
We study the asymptotic behaviour of stochastic processes that are generated by sums of partial sums of i.i.d. random variables and their renewals. We conclude that these processes…
