On the tail dependence in bivariate hydrological frequency analysis

Dependence Modeling, 2015
In Bivariate Frequency Analysis (BFA) of hydrological events, the study and quantification of the dependence between several variables of interest is commonly carried out through Pearson’s correlation (r), Kendall’s tau (τ) or Spearman’s rho (ρ).

Characterizations of a family of bivariate Pareto distributions

Statistica, 2015
In the present paper, we study properties of a family of bivariate Pareto distributions. The well known dullness property of the univariate Pareto model is extended to the bivariate setup. Two measures of income inequality viz.

A superintegrable finite oscillator in two dimensions with SU(2) symmetry

, 2012
A superintegrable finite model of the quantum isotropic oscillator in two dimensions is introduced. It is defined on a uniform lattice of triangular shape. The constants of the motion for the model form an SU(2) symmetry algebra.
