• #### Identities with squares of binomial coefficients: An elementary and explicit approach ﻿

(Mathematical Institute of the Serbian Academy of Sciences and Arts, 2016)
In 2014, Slavik presented a recursive method to find closed forms for two kinds of sums involving squares of binomial coefficients. We give an elementary and explicit approach to compute these two kinds of sums. It is based ...
• #### An Indicator Operator Algorithm for Solving a Second Order Intuitionistic Fuzzy Initial Value Problem ﻿

(Matematikçiler Derneği, 2016)
L. Zadeh [1] was the first who introduced the concept of fuzzy settheory as an extension of the classical notion of the set theory. He remindedpeople that things are not always black or white; there may besome grey colours ...
• #### Intelligent Mathematics II: Applied Mathematics and Approximation Theory ﻿

(Springer, 2016)
This special volume is a collection of outstanding more applied articles presented in AMAT 2015 held in Ankara, May 28-31, 2015, at TOBB Economics and Technology University. The collection is suitable for Applied and ...
• #### Intuitionistic Fuzzy Initial Value Problems - An Application ﻿

(Hacettepe UniversityHacettpe Üniversitesi, 2019)
In this paper, by using the properties of ?\alpha? and ?\beta? cuts of intuitionistic fuzzy numbers, we have firstly proposed a method to find the general solution of the second order initial value problem with intuitionistic ...
• #### Korovkin theorems on weighted spaces: revisited ﻿

(Springer, 2017-12)
In this note, using the idea of the late Professor Gadjiev (Mat Zametki 20(5):781-786, 1976), we give new, direct and easy proofs of the Korovkin theorems for positive linear operators acting on weighted spaces. Recent ...
• #### L-Polynomials of the Curve ﻿

(Springer Verlag, 2015)
Let chi be a smooth, geometrically irreducible and projective curve over a finite field F-q of odd characteristic. The L-polynomial L-chi(t) of chi determines the number of rational points of chi not only over F-q but also ...
• #### A Mathematical Model Of Hepatitis B Transmission In Turkey ﻿

(Ankara UniversityAnkara Üniversitesi, 2019)
Hepatitis B infection is one of the serious viral infections that is treating the global health. Turkey has an intermediate endemicity for hepatitis B. In this study, a classical SIR model for hepatitis B virus (HBV) ...
• #### A matrix approach to some second-order difference equations with sign-alternating coefficients ﻿

(Taylor and Francis Ltd., 2020-02)
In this paper, we analyse and unify some recent results on the double sequence {yn,k}, for n, k ? 1, defined by the second-order difference equation (Formula presented.) with (Formula presented.) and (Formula presented.), ...
• #### The Matrix of Super Patalan Numbers and its Factorizations ﻿

(University of Nis, 2017)
Matrices related to Patalan and super-Patalan numbers are factored according to the LU-decomposition. Results are obtained via inspired guessings and later proved using methods from Computer Algebra.
• #### Modified neural network operators and their convergence properties with summability methods ﻿

(Springer, 2020-07)
We study the approximation properties of Cardaliaguet-Euvrard type neural network operators. We first modify the operators in order to get the uniform convergence, later we use regular summability matrix methods in the ...
