Crossed semimodules of categories and schreier 2-categories
(Tbilisi Centre Math Sci, 2018)
The main idea of this paper is to introduce the notion of a Schreier 2-category and of a crossed semimodule over categories and to prove the categorical equivalence between their categories.
Global dynamics of a cooperative discrete system in the plane
(World Scientific Publ Co Pte Ltd, 2018)
In this paper, we consider the cooperative system x(n+1) = ax(n) + by(n)(2)/1 + y(n)(2), y(n+1) = cx(n)(2)/1 + x(n)(2) + dy(n), n = 0, 1, ... , where all parameters a, b, c, d are positive numbers and the initial conditions ...
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 ...
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 ...
On orders induced by implications
(Univ Sistan & Baluchestan, 2019)
In this paper, the orders induced by the residual implications obtained from uninorms are investigated. A necessary and sufficient condition is presented so that the ordinal sum of fuzzy implications satisfies the law of ...
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 ...
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 ...
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 ...
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 ...
