Quantum Cooperative Games

We study two forms of a symmetric cooperative game played by three players, one classical and other quantum. In its classical form making a coalition gives advantage to players and they are motivated to do so. However in its quantum form the advantage is lost and players are left with no motivation to make a coalition.Comment: Revised in the light of referee's comments. Submitted to Physics Letters A.

Backwards-induction outcome in a quantum game

In economics duopoly is a market dominated by two firms large enough to influence the market price. Stackelberg presented a dynamic form of duopoly that is also called `leader-follower' model. We give a quantum perspective on Stackelberg duopoly that gives a backwards-induction outcome same as the Nash equilibrium in static form of duopoly also known as Cournot's duopoly. We find two qubit quantum pure states required for this purpose.Comment: Revised in the light of referee's comments. Latex, 16 pages, 2 figures, To appear in Phy. Rev.

The Refined Topological Vertex

We define a refined topological vertex which depends in addition on a parameter, which physically corresponds to extending the self-dual graviphoton field strength to a more general configuration. Using this refined topological vertex we compute, using geometric engineering, a two-parameter (equivariant) instanton expansion of gauge theories which reproduce the results of Nekrasov. The refined vertex is also expected to be related to Khovanov knot invariants.Comment: 70 Pages, 23 Figure

Persuasive Strategies Used by Agung Sedayu Group in the Infomercial, Metro TV

This study is conducted to find out the types of persuasive strategies which were used in Agung Sedayu Group's infomercial. It is aimed to seek the types of persuasive strategies used by the hosts and the representative team of Agung Sedayu Group in the infomercial. The writer uses the theories of persuasive strategies by Beebe (2012). The types of persuasive strategies theories are enhancing your credibility, using logic and evidence, and using emotion to persuade. In addition, the writer uses theory of social factor by Holmes (2001) as the supporting theory. This research uses qualitative supported by quantitative methods to reveal which strategy that mostly used by the participants. In the analysis, the writer found out that the most dominant persuasive strategy used by the hosts is using emotion to persuade 161 (31.8%). Moreover, the most dominant persuasive strategy used by the representative team is enhancing your credibility 113 (22.3%)
