Uniform stabilization of the Petrovsky-Wave Nonlinear coupled system with strong damping
(Işık University Press, 2023-07)This paper concerns the well-posedness and uniform stabilization of the Petrovsky-Wave Nonlinear coupled system with strong damping. Existence of global weak solutions for this problem is established by using the Galerkin ... -
Uniqueness and stability of solutions for a coupled system of nabla fractional difference boundary value problems
(Işık University Press, 2022)In this article, we obtain sufficient conditions on existence, uniqueness and Ulam–Hyers stability of solutions for a coupled system of two-point nabla fractional difference boundary value problems, using Banach, Brouwer ... -
Unit graph of type - 2
(Işık University Press, 2022)The unit graph of ring R was introduced in commutative rings by Vasantha Kandasamy[27]. In this short note, we introduce the concept namely “Unit graph of type-2” denoted by UG2(R) in associative rings R and announced a ... -
Upper bound for third Hankel determinant of a class of analytic functions
(Işık University Press, 2023-10)We establish upper bounds for second Hankel determinant, the Fekete-Szegö functional and third Hankel determinant for normalized analytic functions f ? W?(?, ?),W?(?, ?) = { f : Re ((1 ? ? + 2?)f(z)/z+ (? ? 2?)f?(z) + ... -
Upper bounds for covering total double Roman domination
(Işık University Press, 2023-07)Let G = (V, E) be a finite simple graph where V = V (G) and E = E(G). Suppose that G has no isolated vertex. A covering total double Roman dominating function (CT DRD function) f of G is a total double Roman dominating ... -
Using implicit relation to prove common coupled fixed point theorems for two hybrid pairs of mappings
(Işık University Press, 2016)Using implicit relation we establish two common coupled fixed point theorems under the conditions of weakly commutativity and w?compatibility on a complete metric space, which is not partially ordered. We do not use the ... -
The v-invariant ?2 sequence spaces
(Işık University Press, 2011-08-01)In this paper we define v? invariatness of a double sequence space of ? and examine the v? invariatness of the double sequence space of ?. Furthermore, we give duals of double sequence space of ?. -
Variable mesh discretization of system of nonlinear singular boundary value problems

Variation formulas of solution for a controlled functional-differential equation considering delay perturbation
(Işık University Press, 2011-03-05)Variation formulas of solution are proved for a controlled non-linear functionaldifferential equation with constant delay and the continuous initial condition. In this paper, the essential novelty is the effect of delay ... -
Vertex coloring edge weightings of some square graphs
(Işık University Press, 2021)A k-edge-weighting w of a graph G is an assignment of integer weight, w(e) ? {1, 2, . . . , k}, to each edge e. A k-edge-weighting w induces a vertex coloring c by defining c(u) = P u?e w(e) for every u ? V (G), where u ? ... -
A view on fuzzy Peano space and its application on rail connectivity network
(Işık University Press, 2022)By using fuzzy path connectedness of a fuzzy topological space (X, T), a wide class of a space named as the fuzzy Peano space has been defined in this paper. Some of the interesting properties of a Fuzzy Peano Space are ... -
VL Index and bounds for the tensor products of F?Sum graphs

A weighted goal programming approach to fuzzy linear regression with quasi type-2 fuzzy input-output data
(Işık University Press, 2016)This study attempts to develop a regression model when both input data and output data are quasi type-2 fuzzy numbers. To estimate the crisp parameters of the regression model, a linear programming model is proposed based ... -
