An Axiomatization of an Exponential Similarity Function [PDF]

open access: yesMathematical Social Sciences, 2008
Abstract An individual is asked to assess a real-valued variable y based on certain characteristics x  = ( x 1 ,…, x m ), and on a database consisting of n observations of ( x 1 ,…, x m , y ). A possible approach to combine past observations of x and y with the current values of x to generate an assessment of y is similarity ...

Brownian Super-exponents [PDF]

open access: yes, 2006
We introduce a transform on the class of stochastic exponentials for d-dimensional Brownian motions. Each stochastic exponential generates another stochastic exponential under the transform.

On Coefficient Inequalities of Starlike Functions Related to the q-Analog of Cosine Functions Defined by the Fractional q-Differential Operator

open access: yesFractal and Fractional, 2023
This article extends the study of q-versions of analytic functions by introducing and studying the association of starlike functions with trigonometric cosine functions, both defined in their q-versions.

QUANTUM EXPONENTIAL FUNCTION [PDF]

open access: yesReviews in Mathematical Physics, 2000
A special function playing an essential role in the construction of quantum "ax+b"-group is introduced and investigated. The function is denoted by Fℏ(r,ϱ), where ℏ is a constant such that the deformation parameter q2=e-iℏ. The first variable r runs over non-zero real numbers; the range of the second one depends on the sign of r: ϱ=0 for r>0 and ϱ=±
