AN ALGORITHM FOR ODD GRACEFULNESS OF THE TENSOR PRODUCT OF TWO LINE GRAPHS [PDF]

open access: yes, 2021
An odd graceful labeling of a graph G = (V E, ) is a function f V G E G : ( ) {0,1,2, . . .2 ( ) 1} → − such that | ( ) ( )| f u f v − is odd value less than or equal to 2 ( ) 1 E G − for any , ( ) u v V G ∈ .

Special Graceful Labelings of Irregular Fences and Lobsters

open access: yesUniversal Journal of Mathematics and Applications, 2019
Irregular fences are subgraphs of $P_m \times P_n$ formed with $m$ copies of $P_n$ in such a way that two consecutive copies of $P_n$ are connected with one or two edges; if two edges are used, then they are located in levels separated an odd number of ...

Divergent Synthesis of Möbius and Hückel N‐Heterocycloarenes From a Common Macrocyclic Backbone

open access: yesAngewandte Chemie, EarlyView.
In the divergent synthesis of Möbius and Hückel N‐heterocycloarenes from a common macrocyclic precursor, the annulation reaction dictates topology: Scholl reaction gives Möbius topology, while InCl3‐mediated alkyne annulation gives Hückel topology. The Möbius N‐heterocycloarene is unevenly contorted as revealed by crystal structure, and the Hückel N ...

E-cordial Labeling for Cartesian Product of Some Graphs [PDF]

open access: yes, 2011
We investigate E-cordial labeling for some cartesian product of graphs. We prove that the graphs Kn × P2 and Pn × P2 are E-cordial for n even while Wn × P2 andK1,n × P2 are E-cordial for n odd.

Graphs with edge-odd graceful labelings

open access: yesInternational Mathematical Forum, 2013
Solairaju and Chithra [3] introduced a new type of labeling of a graph G with q edges called an edge-odd graceful lebeling if there is a bijection f from the edges of the graph to the set {1, 3, 5, . . . , 2q − 1} such that, when each vertex is assigned the sum of all the edges incident to it mod 2q, the resulting vertex labels are distinct.

Kinetic Contribution to the Arbitrary Order Odd Frequency Moments of the Dynamic Structure Factor

open access: yesContributions to Plasma Physics, EarlyView.
ABSTRACT An exact expression is derived for the kinetic contribution to the odd (arbitrary order) frequency moments of the dynamic structure factor via a finite summation that features averages of even (all lower orders) powers of the momentum over the exact momentum distribution.

Creating a Masterpiece. The Road to (and Beyond) Woodward and Hoffmann's 1969 Angewandte Chemie Treatise

open access: yesThe Chemical Record, EarlyView.
This publication describes how R. B. Woodward and Roald Hoffmann crafted their masterpiece publications. Illustrations include Woodward's first draft of the famous “Violations There are none. Nor can violations be expected of so fundamental a principle of maximum bonding.” Original but discarded text shows the stepwise paths toward the W‐H masterpieces.

Becoming Dostoevsky (how Rowan Williams opens up Bakhtin)

open access: yesModern Theology, EarlyView.
Abstract With the end of Communism in Russia, non‐materialist contexts were enthusiastically restored to Mikhail Bakhtin's globally famous ideas of carnival, dialogism, and polyphony. This essay surveys Rowan Williams's 2008 study Dostoevsky: Language, Faith + Fiction as a major contribution to this effort, concentrating on those general philosophical ...
