We study the Hamilton-Jacobi (HJ) approach for a two-person zero-sum differential game with state constraints and where controls of two players are coupled within dynamics, cost functions. It is known such problems that value function may be discontinuous its characterization by means an HJ equation requires some controllability assumptions involving dynamics set constraints. In this work, we c...

Rational choice when preferences are not required to be transitive and complete has been discussed in the literature for years. In this article transitivity and completeness of the preference relation is also not assumed. It will be shown that nevertheless the existence of a competitive equilibrium can be proven when those properties are replaced by a domination property which allows that there...

We present a comprehensive study of the use of value precedence constraints to break value symmetry. We first give a simple encoding of value precedence into ternary constraints that is both efficient and effective at breaking symmetry. We then extend value precedence to deal with a number of generalizations like wreath value and partial interchangeability. We also show that value precedence is...

There is disparity in access to Information and Communication Technologies between male and female especially in developing countries. This study did a gender analysis of access and use of ICTs in Ekiti state, Nigeria. Multistage sampling procedure was used to select 178 respondents. Data collected were analysed using descriptive statistics and t-test at α0.05. Radio (198.7), mobile phones (186...
