Stability analysis of a fractional order coronavirus(COVID-19) epidemic model
(Işık University Press, 2023-10)In this paper a six-compartmental coronavirus(COVID-19) epidemic model is developed. We have divided the total population into five classes, namely susceptible, exposed, infected, treatment, recovered and the concentration ... -
An iterative approach for fuzzy multi objective linear fractional programming problem
(Işık University Press, 2023-10)In this paper, we introduce an iterative method for the solution of fully fuzzy single and multi objective linear fractional programming problems with out converting them into equivalent crisp forms. By introducing fuzzy ... -

Laceability properties in the image graph of Prism graphs
(Işık University Press, 2023-10)A connected graph G is termed Hamiltonian-t-laceable if there exists in it a Hamiltonian path between every pair of vertices u and v with the property d(u, v) = t, 1 ? t ? diam(G), where t is a positive integer. In this ... -
Certain subclasses of analytic function by S?l?gean q-differential operator
(Işık University Press, 2023-10)The theory of q-analysis has many applications in various sub-fields of mathematics and quantum physics. In the present article, we define the class Tn(?, ?; q) using the S?l?gean q-differential operator. For functions ... -
A multi criteria group decision making approach based on fuzzy measure theory to assess the different gene regions used in rodent species
(Işık University Press, 2023-10)Many mitochondrial and nuclear gene regions are used in phylogenetic and taxonomic studies to investigate the historical background of the species and to present the hierarchy of the species. In this paper, we consider the ... -
Shifted Legendre polynomial solutions of nonlinear stochastic Itô - Volterra integral equations
