  1. Regularization by Free Additive Convolution, Square and Rectangular Cases

    Serban T. Belinschi, Florent Benaych-Georges, Alice Guionnet in Complex Analysis and Operator Theory
    Article 15 July 2008
  2. Rectangular random matrices, related convolution

    We characterize asymptotic collective behavior of rectangular random matrices, the sizes of which tend to infinity at different rates. It appears...

    Article 08 April 2008
  3. A limit theorem for products of free unitary operators

    This paper establishes necessary and sufficient conditions for the sequence of products of freely independent unitary operators to converge in...

    Article 21 August 2007
  4. The Lebesgue decomposition of the free additive convolution of two probability distributions

    We prove that the free additive convolution of two Borel probability measures supported on the real line can have a component that is singular...

    Serban Teodor Belinschi in Probability Theory and Related Fields
    Article 19 September 2007
  5. Infinitely divisible distributions for rectangular free convolution: classification and matricial interpretation

    In a previous paper (Benaych-Georges in Related Convolution 2006), we defined the rectangular free convolution ⊞ λ . Here, we investigate the related...

    Article 06 January 2007
  6. Remarks on the r and Δ convolutions

    In this paper we study the properties of the r –deformation introduced in [B1]. We observe that the associated convolution coming from the...

    Article 16 February 2006
  7. Cumulants for random matrices as convolutions on the symmetric group

    In this paper, we show that free cumulants can be naturally seen as the limiting value of ``cumulants of matrices''. We define these objects as...

    M. Capitaine, M. Casalis in Probability Theory and Related Fields
    Article 10 November 2005
  8. Failure of the Raikov Theorem for Free Random Variables

    We show that the sum of two free random variables can have a free Poisson law without any of them having a free Poisson law.
    Florent Benaych-Georges in Séminaire de Probabilités XXXVIII
    Chapter 2005
  9. Free fisher information and amalgamated freeness

    The notion of operator-valued free Fisher information was introduced. It is a generalization of free Fisher information which was defined by D....

    Article 01 October 2004
  10. Multivariable moment problems

    In this paper we solve moment problems for Poisson transforms and, more generally, for completely positive linear maps on unital C * -algebras...

    Gelu Popescu in Positivity
    Article 01 December 2004
  11. The Lévy-Itô decomposition in free probability

    In this paper we prove the free analog of the Lévy-Itô decomposition for Lévy processes. A significant part of the proof consists of introducing free...

  12. Atoms and regularity for measures in a partially defined free convolution semigroup

    Consider a Borel probability measure μ on the real line, and denote by { μ t : t ≥1} the free additive convolution semigroup defined by Nica and...

    S. T. Belinschi, H. Bercovici in Mathematische Zeitschrift
    Article 27 April 2004
  13. Non injectivity of the q-deformed von Neumann algebra

    In this paper we prove that the von Neumann algebra generated by q-gaussians is not injective as soon as the dimension of the underlying Hilbert...

    Alexandre Nou in Mathematische Annalen
    Article 23 June 2004
  14. Free transportation cost inequalities via random matrix approximation

    By means of random matrix approximation procedure, we re-prove Biane and Voiculescu’s free analog of Talagrand’s transportation cost inequality for...

    For an inclusion of the form \(\mathbb{C} \subseteq M_n (\mathbb{C})\)...
    Conference paper 2004
  16. The Atoms of the Free Multiplicative Convolution of Two Probability Distributions

    We determine the atoms of the free multiplicative convolution of two measures supported on the unit circle or on the positive real line. Analogous...

    Serban Teodor Belinschi in Integral Equations and Operator Theory
    Article 01 August 2003
  17. Logarithmic Sobolev Inequalities, Matrix Models and Free Entropy

    We give two applications of logarithmic Sobolev inequalities to matrix models and free probability. We also provide a new characterization of...
