An iterative method for solving time-fractional partial differential equations with proportional delays
(Işık University Press, 2023-01)
This article deals with an iterative method which is a new formulation of Adomian decomposition method for solving time-fractional partial differential equations (TFPDEs) with proportional delays. The fractional derivative ...
Local distance irregular labeling of graphs
(Işık University Press, 2023-01)
We introduce the notion of distance irregular labeling, called the local distance irregular labeling. We define ? : V (G) ?? {1, 2, . . . , k} such that the weight calculated at the vertices induces a vertex coloring if ...
K-product cordial labeling of fan graphs
(Işık University Press, 2023-01)
Let f be a map from V (G) to {0, 1, ..., k ? 1} where k is an integer, 1 ? k ? |V (G)|. For each edge uv assign the label f(u)f(v)(mod k). f is called a k-product cordial labeling if |vf (i) ? vf (j)| ? 1, and |ef (i) ? ...
On the vertex degree polynomial of graphs
(Işık University Press, 2023-01)
A novel graph polynomial, termed as vertex degree polynomial, has been conceptualized, and its discriminating power has been investigated regarding its coefficients and the coefficients of its derivatives and their relations ...
Some new existence results for boundary value problems involving ?-Caputo fractional derivative
(Işık University Press, 2023-01)
This paper concerns the boundary value problem for a fractional differential equation involving a generalized Caputo fractional derivative in b?metric spaces. The used fractional operator is given by the kernel k(t, s) = ...
Optimal control analysis of the malaria model with saturated treatment
(Işık University Press, 2023-01)
Malaria is a disease which is transmitted through the bite of an infected Anopheles mosquito. According to WHO report, 400.000 people die worldwide from malaria disease annually. We extend a Susceptible-Infective-Susceptible ...
Solution of the Volterra-Fredholm integral equations via the Bernstein polynomials and least squares approach
(Işık University Press, 2023-01)
We develop a numerical scheme to solve a general category of VolterraFredholm integral equations. For this purpose, the Bernstein polynomials and their features have been used. We convert the main equation into a set of ...
Formally self-dual codes over F?[u]/‹u?›
(Işık University Press, 2023-01)
In this work, Gray images of formally self-dual codes over the ring S? = F?[u]/‹u?› and some of their construction methods are considered. As a result, a considerable number of good formally self-dual binary codes with ...
The hub number of a fuzzy graph
(Işık University Press, 2023-01)
In this paper, we introduced the concepts of hub number in fuzzy graph and is denoted by h(G). The hub number of fuzzy graph G is the minimum fuzzy cardinality among all minimal fuzzy hub sets . We determine the hub number ...
Applying multiquadric quasi-interpolation to solve Fokker-Planck equation
(Işık University Press, 2023-01)
The Fokker-Planck equation (FPE) arises in various fields in physics, chemistry, natural science. It is difficult to obtain analytical solutions, accordingly we resort to numerical methods. In this study, we present a ...
