Factorization method and general second order linear difference equation
This paper addresses an investigation on a factorization method for
difference equations. It is proved that some classes of second order linear
difference operators, acting in Hilbert spaces, can be factorized using a pair
of mutually adjoint first order difference operators. These classes encompass
equations of hypergeometic type describing classical orthogonal polynomials of
a discrete variable
R(p,q)- analogs of discrete distributions: general formalism and application
In this paper, we define and discuss - deformations of
basic univariate discrete distributions of the probability theory. We mainly
focus on binomial, Euler, P\'olya and inverse P\'olya distributions. We discuss
relevant deformed factorial moments of a random variable,
and establish associated expressions of mean and variance. Futhermore, we
derive a recursion relation for the probability distributions. Then, we apply
the same approach to build main distributional properties characterizing the
generalized Quesne quantum algebra, used in physics. Other known results
in the literature are also recovered as particular cases
