In this paper we work toward the Homflypt skein module of the lens spaces L(p, 1), S(L(p, 1)), using braids. In particular, we establish the connection between S(ST), the Homflypt skein module of the solid torus ST, and S(L(p, 1)) and arrive at an infinite system, whose solution corresponds to the computation of S(L(p, 1)). We start from the Lambropoulou… (More)
A new marketing tool is proposed based on games for smart devices like smart phones and tablets. Game experience is extended to real life, with riddles in specific locations, motivating the user to visit sites of interest. A simple prototype has been developed and several marketing scenarios have been evaluated..
