Realizing Degree Sequences with Graphs Having Nowhere-Zero 3-Flows
The following open problem was proposed by Archdeacon: Characterize all graphical sequences π such that some realization of π admits a nowhere-zero 3-flow. This open problem is solved in this paper with the following complete characterization: A graphical sequence π = (d1, d2, . . . , dn) with minimum degree at least two has a realization that admits a nowhere-zero 3-flow if and only if π 6= (3...

California has embarked on a bold experiment in trying to reduce carbon emissions without causing undue harm to the state’s economy. The goal is made more difficult by the State’s inability to erect protective tariffs to restrict imports from states and countries without costly carbon regulations.

متن کاملEvaluation of Economy in a Zero-sum Perfect Information Game
A zero-sum perfect information game is one where every player knows all the moves. Chess is a good example where the object is to checkmate or capture the enemy king. One important feature of checkmates, especially in chess problem composition, is economy. This paper proposes a computational function to evaluate the economy of checkmate configurations on the chessboard. Several experiments were...
متن کاملMerchant Sharing Towards a Zero Marginal Cost Economy
This paper is the first attempt to formalize a new field of economics; studding the Intangibles Goods available on the Internet. We are taking advantage of the digital world's specific rules, in particular the zero marginal cost, to propose a theory of trading & sharing unified. A function based money is created as a worldwide currency; ⊔ (pronounced /k2p/). We argue that our system discourage ...
