Equitable and outdegree equitable domination number of graphs
(Işık University Press, 2023-10)Let G = (V, E) be a simple graph. A subset D of V is said to be a dominating set of G, if each vertex in V is either in D or has a neighbour in D. A subset D of V is said to be an equitable dominating set of G, if for every ... -
Hyperbolic type harmonically convex function and integral inequalities
(Işık University Press, 2023-10)In this paper, we define a new class of harmonic convexity i.e. Hyperbolic type harmonic convexity and explore its algebraic properties. Employing this new definition, some integral inequalities of Hermite-Hadamard type ... -
Alternating method for solving a biharmonic inverse problem in detection of Robin coefficients
(Işık University Press, 2023-10)In this paper, we are interested in an inverse problem of detection of corrosion for a biharmonic equation which consists to determine the Robin coefficients in the inaccessible part of the boundary from the Riquiert-Neumann ... -
Face antimgaic labeling of double duplication for some special graphs
(Işık University Press, 2023-10)The main objective of the paper is to determine (a, d)? face antimagic labeling for the double duplication of all vertices by edges of ladder, tadpole and m-copies of path graphs. Also, if a graph G is (a, d)? face antimagic ... -

(Işık University Press, 2023-10)Let G be a graph with vertices v1, v2, . . . , vn and let di be the degree of vi. The Zagreb matrix of the graph G is the square matrix of order n whose (i, j)-entry is equal to di + dj if the vertices vi and vj are adjacent, ... -

Invariances of strongly continuous quasi semigroups and disturbance decoupling problems
(Işık University Press, 2023-10)In this paper, invariances of a subspace of a Hilbert space under strongly continuous quasi semigroup (C?-quasi semigroup) are characterized. The invariancerelationship between the C?-quasi semigroups and its infinitesimal ... -
Critical point results and their applications
(Işık University Press, 2023-10)The purpose of this paper is to study the concept of a critical point in complete cone metric spaces and its application in Ekeland type variational principle. For this, we consider the concept of a ?-space, which is weaker ... -
The homogeneous q-difference operator and the related polynomials
(Işık University Press, 2023-10)We create the homogeneous q-difference operator Ee(a, b; ?) as an extension of the exponential operator E(b?). A new polynomials hn(a, b, x|q?1) are defined as an extension of the q?1-Rogers-Szegö polynomial hn(a, b|q?1). ... -
Signless Laplacian polynomial for splice and link of graphs
(Işık University Press, 2023-10)The signless Laplacian matrix of a graph G is Q(G) = A(G) + D(G), where A(G) is the adjacency matrix and D(G) is the diagonal degree matrix of a graph G. The characteristic polynomial of the signless Laplacian matrix is ... -
