Analysis of an epidemic model for transmitted disease in two age classes
(Hacettepe Journal of Mathematics and Statistics, 202006)Infectious diseases are a serious problem for public health and spark the interest in interdisciplinary studies. In this paper, we present two mathematical models describing a possible scenario for infectious diseases. The ... 
Approximation by maxmin operators: A general theory and its applications
(Elsevier B.V., 20200901)In this study, we obtain a general approximation theorem for maxmin operators including many significant applications. We also study the error estimation in this approximation by using Hölder continuous functions. The ... 
Asset price dynamics for a twoasset market system
(American Institute of Physics Inc., 201902)We present a mathematical model for a market involving two stocks which are traded within a single homogeneous group of investors who have similar motivations and strategies for trading. It is assumed that the market ... 
Asymmetric generalizations of the Filbert matrix and variants
(Mathematical Institute of the Serbian Academy of Sciences and Arts, 2014)Four generalizations of the Filbert matrix are considered; with additional asymmetric parameter settings. Explicit formula are derived for the LUdecompositions, their inverses, and the inverse matrix. The approach is ... 
A nonlinear generalization of the Filbert matrix and its Lucas analogue
(Taylor and Francis Ltd., 201901)In this paper, we present both a new generalization and an analogue of the Filbert matrix (Formula presented.) by the means of the Fibonacci and Lucas numbers whose indices are in nonlinear form (Formula presented.) for ... 
Closed Form Evaluation Of Melham's Reciprocal Sums
(Univ Miskolc Inst Math, 2017)Recently Melham [1] gives closed formul ae for certain finite reciprocal sums. In this paper, we present a different approach to compute these sums in closed form. Our approach is straightforward and simple. First we ... 
Closed form evaluation of restricted sums containing squares of Fibonomial coefficients
(Politechnica University of Bucharest, 2016)We give a systematic approach to compute certain sums of squares Fibonomial coefficients with powers of generalized Fibonacci and Lucas numbers as coefficients; the range of the summation is not the natural one but about ... 
Closed form evaluation of sums containing squares of Fibonomial coefficients
(De Gruyter Open Ltd, 201606)We give a systematic approach to compute certain sums of squares of Fibonomial coefficients with finite products of generalized Fibonacci and Lucas numbers as coefficients. The technique is to rewrite everything in terms ... 
The concept of Hukuhara derivative and Aumann integral for intuitionistic fuzzy number valued functions
(Kyrgyz Turkish Manas UniversityKırgızistan Türkiye Manas Üniversitesi, 2018)In this paper we have rstly dened a metric based on the Hausdor metric in intuitionistic fuzzy environment and studied its properties. Then we have proved that the metric space of intuitionistic fuzzy number valued ... 
Decompositions of the Cauchy and FerrersJackson polynomials
(Udruga Matematicara Osijek, 2016)Recently, Witula and Slota have given decompositions of the Cauchy and FerrersJackson polynomials [Cauchy, FerrersJackson and Chebyshev polynomials and identities for the powers of elements of some conjugate recurrence ... 
Double binomial sums and double sums related with certain linear recurrences of various order
(Chiang Mai University, 20180501)In this paper, we derive new double binomial sums families related with generalized second, third and certain higher order linear recurrences. We also present various parametric generalizations of some results of [1, 2]. ... 
Estimation of the Hurst parameter for fractional Brownian motion using the CMARS method
(Elsevier Science Bv, 201403)In this study, we develop an alternative method for estimating the Hurst parameter using the conic multivariate adaptive regression splines (CMARS) method. We concentrate on the strong solutions of stochastic differential ... 
Evaluation of Hessenberg Determinants via Generating Function Approach
(University of Nis, 2017)In this paper, we will present various results on computing of wide classes of Hessenberg matrices whose entries are the terms of any sequence. We present many new results on the subject as well as our results will cover ...
