In 2006, Suzuki, and Akbari & Alipour independently presented a necessary and sufficient condition for edge-colored graphs to have a heterochromatic spanning tree, where a heterochromatic spanning tree is a spanning tree whose edges have distinct colors. In this paper, we propose f -chromatic graphs as a generalization of heterochromatic graphs. An edge-colored graph is f -chromatic if each col...

In the modeling, the probabili...

• Let G be a graph. For subset X of V ( ), the switching σ is signed graph obtained from by reversing signs all edges between and ) ∖ . A( adjacency matrix An eigenvalue called main if it has an eigenvector sum whose entries not equal to zero. Two equivalent graphs share same spectrum, while they may have different eigenvalues. Akbari et al. (2021) conjectured that let ≠ K 2 , 4 { e } Then ther...

abstract the present research was done to evaluate proline, proteins and sugars of flower buds of pistachio trees during phonological stages. this study was conducted using a split-plot design with three replications considered time as main factor (5 stages) and cultivars (ahmad-aghaee, ouhadi, kaleh-ghochi and akbari) as secondary factor. the experiment was conducted at ferdowsi university of ...

In this article, the equations governing constant ferromagnetic current are investigated. The Lorentz force restrains ferrofluid flow in a semi-porous valve. Analyzes were performed on three sub-particle fluids: kerosene and blood, water magnetite. Modeling Cartesian coordinate system using relevant was A slight thinning should be considered lower part of channel. This research has used two Akb...
