Existence and uniqueness results for an initial-boundary value problem of parabolic operator-differential equations in a weight space
(Işık University Press, 2021)In this article, through the coefficients of the second order parabolic operatordifferential equation, the regular solvability problem with initial-boundary conditions is proved in a weight space. The association between ... -
Extending the notion of 3-fold-3-point-splitting from graphs to binary matroids
(Işık University Press, 2021)Slater defined r-fold-n-point-splitting operation on graphs and proved that, if G is an n-connected graph and H is a graph obtained from G by an r-fold-n-pointsplitting, then H is n-connected. In this article we extend ... -
Fixed points in φ-ordered partial quasi-metric space
(Işık University Press, 2021)We obtain fixed points for an order preserving mapping in a preordered left p-complete partial quasi-metric space using a preorder induced by an appropriate function. In particular, we do not make use of any contraction condition. -
Fuzzy congruence on MΓ−groups
(Işık University Press, 2021)In this paper, we consider an algebriac structure MΓ− group, which is a generalization of both the concepts module over a nearring and a gamma nearring, introduced by Satyanarayana [12]. In this paper, we define a fuzzy ... -

Minimal restrained monophonic sets in graphs
(Işık University Press, 2021)For a connected graph G = (V, E) of order at least two, a restrained monophonic set S of a graph G is a monophonic set such that either S = V or the subgraph induced by V −S has no isolated vertices. The minimum cardinality ... -
