Grundy coloring of middle graph of wheel graph families
(Işık University Press, 2023-07)A Grundy k-coloring of a graph G is a proper k-coloring of vertices in G using colors {1, 2, · · · , k} such that for any two colors i and j, i < j, any vertex colored j is adjacent to some vertex colored i. The First-Fit ... -

The generalized q-operator r?s and its applications in q-identities
(Işık University Press, 2023-07)Based on the basic hypergeometric series r?s, we construct a new generalized q-operator r?s (a1, . . . , ar b1, . . . , bs ; q, ?c?) and obtain some of its identities. Using these identities, we generalize several well-known ... -
Pair difference cordial labeling of some union of graphs
(Işık University Press, 2023-07)Let G = (V, E) be a (p, q) graph. Define ? = {p/2 if p is even p?1/2 if p is odd and L = {±1, ±2, ±3, · · · , ±?} called the set of labels. Consider a mapping f : V ? L by assigning different labels in L to the different ... -
Novel possibility spherical fuzzy soft set model and its application for a decision making
(Işık University Press, 2023-07)We talk about possibility spherical fuzzy soft set (shortly PSFS set) has much stronger ability than possibility Pythagorean fuzzy soft set (shortly PPFS set) and intuitionistic fuzzy soft set. The PSFS soft set is a ... -
Fuzzy ?-?*-homotopy and fuzzy ?-?*-covering spaces
(Işık University Press, 2023-07)In this paper, the concepts of fuzzy ?-?*-homotopies and fuzzy ?-?*-path homotopies are introduced. The intend of this article is to study the concepts of ?-?*-fundamental group in a fuzzy topological space and fuzzy ... -
Dynamics, control, stability, diffusion and synchronization of modified chaotic colpitts oscillator with triangular wave non-linearity
(Işık University Press, 2022-07)The purpose of this paper is to introduce a new chaotic oscillator. Although different chaotic systems have been formulated by earlier researchers, only a few chaotic systems exhibit chaotic behaviour. In this work, a new ... -

Certain topological indices and related polynomials for polysaccharides
(Işık University Press, 2023-07)A polysaccharide is a large molecule made of many smaller monosaccharides. Monosaccharides are simple sugars, like glucose. Special enzymes bind these small monomers together creating large sugar polymers or polysaccharides. ... -
