A generalized method for the Darboux transformation
(AIP Publishing, 2022)A method is presented to obtain the change in the potential and in the relevant wavefunction of a linear system of ordinary differential equations containing a spectral parameter, when that linear system is perturbed and ... -
Generalized osculating curves of type (n-3) in the n-dimensional Euclidean space
(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 ... -
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 ... -
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 ... -
Group-2-groupoids and 2G-crossed modules
(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 ... -
The impact of the limit q-durrmeyer operator on continuous functions
(Springer, 2024)The limit q-Durrmeyer operator, D-infinity,D-q, was introduced and its approximation properties were investigated by Gupta (Appl. Math. Comput. 197(1):172-178, 2008) during a study of q-analogues for the Bernstein-Durrmeyer ... -
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 ... -
[l(p)](e.r) Euler-riesz difference sequence spaces
(Global Scince Press, 2021)Baar and Braha [1], introduced the sequence spaces l(infinity), C and C-0 of Euler- Cesaro bounded, convergent and null difference sequences and studied their somere properties. Then, in [2], we introduced the sequence ... -
Lattice operations of positive bilinear mappings
(Mathematical Society of the Rep. of China, 2008)In this paper we establish extension theorems for additive mappings ? : A+ ×B+ ? C+, where A, B are Riesz spaces (lattice ordered spaces or vector lattices) and C is an order complete Riesz space, to the whole of A×B, ... -
A modification of approximate random characteristics for a model of Zika virus transmission
