On the Moments of the Trace of a Matrix and Approximations to Its Non- Central Distribution

open access: yesThe Annals of Mathematical Statistics, 1966
Let $\mathbf{A}_1$ and $\mathbf{A}_2$ be two symmetric matrices of order $p, \mathbf{A}_1$, positive definite and having a Wishart distribution [2], [18] with $f_1$ degrees of freedom and $\mathbf{A}_2$, at least positive semi-definite and having a (pseudo) non-central (linear) Wishart distribution [1], [3], [5], [18], [19] with $f_2$ degrees of ...

Multi-charged moments of two intervals in conformal field theory

open access: yesJournal of High Energy Physics, 2022
We study the multi-charged moments for two disjoint intervals in the ground state of two 1 + 1 dimensional CFTs with central charge c = 1 and global U(1) symmetry: the massless Dirac field theory and the compact boson (Luttinger liquid). For this purpose,

Passage-time moments and hybrid zones for the exclusion-voter model [PDF]

open access: yes, 2010
We study the non-equilibrium dynamics of a one-dimensional interacting particle system that is a mixture of the voter model and the exclusion process.

Evaluation of Turbulent Jet Characteristic Scales Using Joint Statistical Moments and an Adaptive Time-Frequency Analysis

open access: yesFluids, 2022
This paper presents an analysis of turbulence characteristic scales and eddy convection velocity of jet flows computed using joint statistical moments, digital filters, and a modified version of the empirical mode decomposition (EMD).

A probablistic proof of the series representation of the MacDonald function with applications

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1998
A series representation of the Macdonald function is obtained using the properties of a probability density function and its moment generating function. Some applications of the result are discussed and an open problem is posed.

Some Results on the Non-Central Multivariate Beta Distribution and Moments of Traces of Two Matrices

open access: yesThe Annals of Mathematical Statistics, 1965
Let $\mathbf{A}_1$ and $\mathbf{A}_2$ be two symmetric matrices of order of $p, \mathbf{A}_1$, positive definite and having a Wishart distribution [2], [12] with $f_1$ degrees of freedom, and $\mathbf{A}_2$, at least positive semi-definite and having a (pseudo) non-central (linear) Wishart distribution ([1], [3], [4], [12], [13]) with $f_2$ degrees of ...
