From 4D Reduced SYM Integrals to Branched-Polymers
Zdzislaw Burda, Bengt Petersson, Marc Wattenberg
We derive analytically one-loop corrections to the effective Polyakov-line operator in the branched-polymer approximation of the reduced four-dimensional supersymmetric Yang-Mills…
Free Levy Matrices and Financial Correlations
Z. Burda, J. Jurkiewicz, M. A. Nowak +2
We consider a covariance matrix composed of asymmetric and free random Levy matrices. We use the results of free random variables to derive an algebraic equation for the resolvent…
Levy Matrices and Financial Covariances
Z. Burda, J. Jurkiewicz, M. A. Nowak +2
In a given market, financial covariances capture the intra-stock correlations and can be used to address statistically the bulk nature of the market as a complex system. We provide…
Free Random Levy Matrices
Z. Burda, R. A. Janik, J. Jurkiewicz +3
Using the theory of free random variables (FRV) and the Coulomb gas analogy, we construct stable random matrix ensembles that are random matrix generalizations of the classical one…
Lattice Models of Random Geometries
Z. Burda
We review models of random geometries based on the dynamical lattice approach. We discuss one dimensional model of simplicial complexes (branched polymers), two dimensional model o…
