About the orders induced by implications satisfying the law of importation
(World Scientific Publ Co Pte Ltd, 2018)In this paper, an order induced by implications on a bounded lattice under some more lenient conditions than the ones given former studies is defined and some of its properties are discussed. By giving an order based on ... -
Some notes on the partial orders induced by a uninorm and a nullnorm in a bounded lattice
(Elsevier Science Bv, 2018)In this paper, an equivalence on the class of nullnorms on a bounded lattice is discussed. Some relationships between the U and V-partial orders are investigated. A necessary and sufficient condition making a bounded lattice ... -
Normal curves in n-dimensional Euclidean space
(Springeropen, 2018)In this paper, we give a generalization of normal curves to n-dimensional Euclidean space. Then we obtain a necessary and sufficient condition for a curve to be a normal curve in the n-dimensional Euclidean space. We ... -
Normality and quotient in crossed modules over groupoids and 2-groupoids
(Kangwon-Kyungki Mathematical Soc, 2019)The aim of this paper is to consider the categorical equivalence between crossed modules within groupoids and 2-groupoids; and then relate normality and quotient in these two categories. -
Crossed semimodules and cat(1)-monoids
(Kangwon-Kyungki Mathematical Soc, 2019)The main idea of this paper is to introduce the notion of cat(1)-monoids and to prove that the category of crossed semimodules C = (A, B, partial derivative) where A is a group is equivalent to the category of cat(1)-monoids. ... -
Some notes on u-partıal order
(Kybernetika, 2019)In this paper, an equivalence on the class of uninorms on a bounded lattice is discussed. Some relationships between the equivalence classes of uninorms and the equivalence classes of their underlying t-norms and t-conorms ... -
A construction method for t-norms on bounded lattices
(Springer International Publishing Ag, 2019)In this paper, a construction method on a bounded lattice from a given t-norm on a subinterval of the bounded lattice is presented. the supremum distributivity of the constructed t-norm by the mentioned method has been ... -
Matrix transformations and compact operators on the binomial sequence spaces
(Kangwon-Kyungki Mathematical Soc, 2019)In this work, we characterize some matrix classes concerning the Binomial sequence spaces b(infinity)(r,s) and b(p)(r;s), where 1 <= p < infinity. Moreover, by using the notion of Hausdorff measure of noncompactness, we ... -
Construction methods for implications on bounded lattices
(Kybernetika, 2019)In this paper, the ordinal sum construction methods of implications on bounded lattices are studied. Necessary and sufficient conditions of an ordinal sum for obtaining an implication are presented. New ordinal sum ... -
Construction methods for uni-nullnorms and null-uninorms on bounded lattice
(Kybernetika, 2019)In this paper, two construction methods have been proposed for uni-nullnorms on any bounded lattices. the difference between these two construction methods and the difference from the existing construction methods have ... -
An extension method for t-norms on subintervals to t-norms on bounded lattices
(Kybernetika, 2019)In this paper, a construction method on a bounded lattice obtained from a given t-norm on a subinterval of the bounded lattice is presented. the supremum distributivity of the constructed t-norm by the mentioned method is ... -
Global stability in a pathogen-specific cd8 immune response prediction model
(Yildiz Technical Univ, 2019)In this study, a system of ordinary differential equations used for modeling pathogen-specific CD8 cell immune response is studied. the positivity and the limitation of the model solutions are proven. the equilibrium points ... -
Inventory model of type (s, S) under heavy tailed demand with infinite variance
(Brazilian Statistical Association, 2019)In this study, a stochastic process X(t), which describes an inventory model of type (s, S) is considered in the presence of heavy tailed demands with infinite variance. the aim of this study is observing the impact of ... -
t-closure operators
(Taylor & Francis Ltd, 2019)In this study, based on the knowledge of the existence of t-norms on an arbitrary given bounded lattice, we introduce t-closure operators with the help of a t-norm on the lattice and a subset of the lattice including the ... -
De Moivre's and Euler's formulas for the matrices of octonions
(Natl Acad Sciences India, 2019)The purpose of this paper is to obtain de Moivre's and Euler's formulas for the matrices of octonions, and to find the powers and the roots of these matrices. A simple method is provided to find the powers of 8x8 matrices ... -
Some new construction methods for t-norms on bounded lattices
(Taylor & Francis Ltd, 2019)In this paper, three methods for constructing triangular norms on a bounded lattice L from t-norm W on sub-lattice of L are investigated. An example is added to reveal the difference of three construction methods. the ... -
Evaluation of the convolution sum sigma(al+bm=n) sigma(l)sigma(m) for (a, b) = (1, 48), (3, 16), (1, 54), (2, 27)
(Wydawnictwo Naukowe Uam, 2019)We determine the convolution sum Sigma(al+bm=n) sigma(l)sigma(m) for (a, b) = (1, 48), (3, 16), (1, 54), (2, 27) for all positive integers n. We then use these evaluations together with known evaluations of other convolution ... -
Split-type octonion matrix
(Wiley, 2019)The split and hyperbolic (countercomplex) octonions are eight-dimensional nonassociative algebras over the real numbers, which are in the form X = x(0)e(0) + Sigma(7)(j=1)x(j)e(j) e(m)'s (0 <= m <= 7) have different ... -
