An almost orthosymmetric bilinear map
Yılmaz, Ruşen (2019)In this paper, as a generalization of the concept of pseudo-almost f-algebra, we deÖne a new concept of almost orthosymmetric bilinear map on a vector lattice and prove that the Arens triadjoint of a positive almost ... -
The binomial almost convergent and null sequence spaces
Bişgin, Mustafa Cemil (2018)In this paper, we introduce the sequence spaces f(Br;s), f0(Br;s) and fs(Br;s) which generalize the Kiri¸sÁiís work [16]. Moreover, we show that these spaces are BK-spaces and are linearly isomorphic to the sequence spaces ... -
Comparison of a random model of Hand-Foot-Mouth Disease model with Gaussian and Laplacian parameters
Bekiryazıcı, Zafer; Hasımoğlu, Saime (Gumushane University, 2022)In this study, we investigate the transmission dynamics of Hand-Foot-Mouth disease (HFMD) using a differential equation system with random parameters. We transform the parameters of the existing deterministic model into ... -
An existing problem for symmetric design: Bruck Ryser Chowla Theorem
Demirci Akarsu, Emek; Öztürk, Safiye (Sakarya University, 2022)Symetric designs are interesting objects of combinatorics, and have some relations with coding theory, difference sets, geometry and finite group theory. They have applications on statistics and design experiments. In ... -
Explicit formulas for exponential of 2×2 split-complex matrices
Çakır, Hasan; Özdemir, Mustafa (Ankara University, 2022)Split-complex (hyperbolic) numbers are ordered pairs of real numbers, written in the form x + jy with j(2) - 1, used to describe the geometry of the Lorentzian plane. Since a null split-complex number does not have an ... -
Generalized osculating curves of type (n-3) in the n-dimensional Euclidean space
Bektaş, Özcan; Bekiryazıcı, Zafer (Ankara University, 2022)In this paper, we give a generalization of the osculating curves to the n-dimensional Euclidean space. Based on the definition of an osculating curve in the 3 and 4 dimensional Euclidean spaces, a new type of osculating ... -
Group-2-groupoids and 2G-crossed modules
Alemdar, Nazmiye; Temel, Sedat (2019)In this paper, we introduce the notion of a group-2-groupoid as a group object in the category of 2-groupoids. We also obtain a 2G-crossed module by using the structure of a group-2-groupoid. Then we prove that the category ... -
Investigation the ergodic distribution of a semi-Markovian inventory model of type (s,S) with intuitive approximation approach
Bektaş Kamışlık, Aslı; Alakoç, Büşra; Kesemen, Tülay; Khaniyev, Tahir (Ankara Yildirim Beyazit University, 2023)This paper concerns a stochastic process X(t) expressing (s, S) type inventory system with intuitive approximation approach. The ergodic distributions of the process X(t) can be analyzed with the help of the renewal function. ... -
On the moments for ergodic distribution of an inventory model of type (s; S) with regularly varying demands having infinite variance
In this study a stochastic process X(t) which represents a semi Markovian inventory model of type (s,S) has been considered in the presence of regularly varying tailed demand quantities. The main purpose of the current ... -
Random process generated by the incomplete Gauss sums
Demirci, Emek Akarsu (2015)In this paper we explore a random process generated by the incomplete Gauss sums and establish an analogue ofweak invariance principle forthese sums. We focusour attentionexclusively on ageneralizationofthe limit distribution ... -
A semi-Markovian renewal reward process with (g) distributed demand
We consider a classical semi-Markovian stochastic model of type (s, S) with Logistic distributed demand random variables. Logistic distribution is a member of special distribution class known as (g) that encounters in many ... -
Some notes on crossed semimodules
Temel, Sedat (Scientific Technical Research Council Turkey, TÜBİTAK, 2022)In this paper, we introduce the notion of lifting via a homomorphism of monoids for a crossed semimodule and give some properties. Further, we characterize actions and coverings of Schreier internal categories in the ... -
Suborbital graphs for the group Gamma(2)
Güler, Bahadır Özgür; Besenk, Murat; Kesicioğlu, Yavuz; Değer, Ali Hikmet (Hacettepe Univ, Fac Sci, 2015)In this paper, we investigate suborbital graphs formed by the action of 2 which is the group generated by the second powers of the elements of the modular group Gamma on (Q) over cap Q. Firstly, conditions for being an ... -
Subsethood measure for picture fuzzy sets and its applications on multicriteria decision making
Köseoğlu, Ali (Gumushane University, 2022)Picture fuzzy set is a direct generalization of intuitionistic fuzzy set and is therefore more capable of dealing with uncertainty while working on real life problems. The concept of inclusion is a subject that is frequently ... -
ℂ, ℍ, O-katsayılı sedeniyonların özel matris gösterimleri ve bazı özellikleri
Bektaş, Özcan (Bitlis Eren Üniversitesi, 2021)Bu makalede ilk olarak sedeniyonlar ile ilgili temel kavramlar verilmiştir. Daha sonra sedeniyonların kompleks (ℂ), kuaterniyon (ℍ) ve oktoniyon (O) katsayılı gösterimlerinden yararlanılarak farklı türden eşlenikleri tanımlanıp, ...
