Long time behavior of the strongly damped wave equation with p-laplacian in Rⁿ
(Işık University Press, 2020)
In this paper, the initial value problem for the one dimensional strongly damped wave equation with p-Laplacian and localized damping in the whole space is concerned. Under the condition 2 < p < 4, the existence of weak ...
Simulation studies for credibility-based multi-objective linear programming problems with fuzzy parameters
(Işık University Press, 2020)
In this paper, hybrid credibility-based multi-objective linear programming models are provided to optimize expected values of objective functions subject to fuzzy chance-constraints. Triangular or non-linear fuzzy numbers ...
On ruled non-degenerate surfaces with Darboux frame in Minkowski 3-space
(Işık University Press, 2020)
In this paper, ruled non-degenerate surfaces with respect to Darboux frame are studied. Characterization of them which are related to the geodesic torsion, the normal curvature and the geodesic curvature with respect to ...
Fuzzy perfect equitable domination excellent trees
(Işık University Press, 2020)
A set D of vertices of a fuzzy graph G is a Perfect Dominating set if every vertex not in D is adjacent to exactly one vertex in D. In this paper, we discuss the concept of equitable excellent fuzzy graph, fuzzy equitable ...
Partition energy of some trees and their generalized complements
(Işık University Press, 2020)
Let G = (V, E) be a graph and Pk = {V1, V2, . . . , Vk} be a partition of V . The k-partition energy of a graph G with respect to partition Pk is denoted by EPk (G) and is defined as the sum of the absolute values of ...
Numerical range and sub-self-adjoint operators
(Işık University Press, 2020)
In this paper, we show that the numerical range of a bounded linear operatör T on a complex Hilbert space is a line segment if and only if there are scalars λ and µ such that T ∗ = λT + µI, and we determine the equation ...
On a class of p(x)-Kirhhoff type problems with Robin boundary conditions and indefinite weights
(Işık University Press, 2020)
In this paper, we consider a class of p(x)-Kirhhoff type problems with Robin boundary conditions and indefinite weights. Under some suitable conditions on the nonlinearities, we establish the existence of at least one ...
Fourth-order accurate method based on half-step cubic spline approximations for the 1d time-dependent quasilinear parabolic partial differential equations
(Işık University Press, 2020)
In this article, we discuss a fourth-order accurate scheme based on cubic spline approximations for the solution of quasilinear parabolic partial differential equations (PDE). The stability of the scheme is discussed using ...
Novel technique for disjointed sum of products
(Işık University Press, 2020)
A classical problem of Boolean theory is to derive a disjointed Sum of Prod-ucts. This work introduces a novel approach for converting Sum of Products into dis-jointed Sum of Products which is based on a novel, generally ...
Hub-integrity polynomial of graphs
(Işık University Press, 2020)
Graph polynomials are polynomials assigned to graphs. Interestingly, they also arise in many areas outside graph theory as well. Many properties of graph polynomials have been widely studied. In this paper, we introduce a ...
