Chromatic quasisymmetric functions
, 2016 We introduce a quasisymmetric refinement of Stanley's chromatic symmetric function. We derive refinements of both Gasharov's Schur-basis expansion of the chromatic symmetric function and Chow's expansion in Gessel's basis of fundamental quasisymmetric ...

Elitism Levels Traverse Mechanism For The Derivation of Upper Bounds on Unimodal Functions [PDF]
, 2012 In this article we present an Elitism Levels Traverse Mechanism that we designed to find bounds on population-based Evolutionary algorithms solving unimodal functions. We prove its efficiency theoretically and test it on OneMax function deriving bounds c{

, 2009 We introduce a new universality class of one-dimensional unimodal dissipative maps. The new family, from now on referred to as the ($z_1,z_2$)-{\it logarithmic map}, corresponds to a generalization of the $z$-logistic map.

On Generalized Inverse Pareto Family of Distributions: Properties and Applications
Journal of Probability and StatisticsIn this paper, we propose new families of generalized inverse Pareto distributions using the T-R{Y} framework. Several choices of the distributions for the random variables T and Y give rise to generalized families of the random variable R, which in this

The q-gradient method for global optimization
, 2013 The q-gradient is an extension of the classical gradient vector based on the concept of Jackson's derivative. Here we introduce a preliminary version of the q-gradient method for unconstrained global optimization. The main idea behind our approach is the

Cosine Weibull Family of Distributions: Properties, Simulation, and Applications to Medical Data
International Journal of Mathematics and Mathematical SciencesBased on the motivation of introducing parsimonious models for efficient analysis of real data, research works of recent times have adopted the use of trigonometric functions in developing new generalized groups of models in the area of distribution ...

Center manifold reduction for large populations of globally coupled phase oscillators
, 2011 A bifurcation theory for a system of globally coupled phase oscillators is developed based on the theory of rigged Hilbert spaces. It is shown that there exists a finite-dimensional center manifold on a space of generalized functions. The dynamics on the

, 2002 Using the Feigenbaum renormalization group (RG) transformation we work out exactly the dynamics and the sensitivity to initial conditions for unimodal maps of nonlinearity $\zeta >1$ at both their pitchfork and tangent bifurcations.

A Laplace Transform Method for Molecular Mass Distribution Calculation from Rheometric Data
, 2017 Polydisperse linear polymer melts can be microscopically described by the tube model and fractal reptation dynamics, while on the macroscopic side the generalized Maxwell model is capable of correctly displaying most of the rheological behavior.
