Computation of connectivity indices of Kulli path windmill graph
(Işık University Press, 2018)
The Kulli path windmill graph P(m)n+1 is the graph obtained by taking m ≥ 2 copies of the graph K1 + Pn for n ≥ 4 with a vertex K1 in common. In this paper, we determine Zagreb, hyper-Zagreb, sum connectivity, general sum ...
q-Starlike functions of order alpha
(Işık University Press, 2018)
For all q ∈ (0, 1) and 0 ≤ α < 1 we define a class of analytic functions, so-called q-starlike functions of order α on the open unit disc D = {z : |z| < 1} . We will study this class of functions and explore some inclusion ...
A critical study of meromorphic starlike functions
(Işık University Press, 2018)
An attempt has been made to introduce a new criterion to make it possible to change meromorphic analytic function into a meromorphic starlike function of particular order. This criterion is based on a differential operator ...
On the moments for ergodic distribution of an inventory model of type (s; S) with regularly varying demands having infinite variance
(Işık University Press, 2018)
In this study a stochastic process X(t) which represents a semi Markovian inventory model of type (s,S) has been considered in the presence of regularly varying tailed demand quantities. The main purpose of the current ...
The theory of representations of groups SO₀(2, 1) and ISO(2, 1). Wigner coefficients of the group SO₀(2, 1)
(Işık University Press, 2018)
This paper is devoted to the representations of the groups SO(2, 1) and ISO(2, 1). Those groups have an important role in cosmology, elementary particle theory and mathematical physics. Irreducible unitary representations ...
Estimating returns to scale using non-radial dea models
(Işık University Press, 2018)
The concept of returns to scale (RTS) is defined as the ratio of the proportionate changes in outputs over the proportionate changes in inputs. By considering the following two facts the current paper develops some non-radial ...
New characterizations of spacelike curves on timelike surfaces through the link of specific frames
(Işık University Press, 2018)
In this work, considering a regular spacelike curve on a smooth timelike surface in Minkowski 3-space, we investigate relations between the mentioned curve’s Darboux and Bishop frames on the timelike surface. Next we obtain ...
Existence of symmetric positive solutions for lidstone type integral boundary value problems
(Işık University Press, 2018)
This paper establishes the existence of even number of symmetric positive solutions for the even order differential equation (−1)n u (2n) (t) = f(t, u(t)), t ∈ (0, 1), satisfying Lidstone type integral boundary conditions ...
Common fixed point theorems for weakly subsequentially continuous mappings in fuzzy metric spaces via implicit relation
(Işık University Press, 2018)
The aim of this paper is to prove some common fixed point theorems for two weakly subsequentially continuous and compatible of type (E) pairs of self mappings satisfying an implicit relation in fuzzy metric spaces. Two ...
On the numerical solution of fractional order differential equations using transforms and quadrature
(Işık University Press, 2018)
In this work, we extended the work of [12] to approximate the solution of fractional order differential equations by an integral representation in the complex plane. The resultant integral is approximated to high order ...
