Unprecedented growth in mobile phone access in emerging economies is the success story of this decade-­‐-­‐ but what about disadvantaged citizens in these countries who continue to confront a digital divide? In many cases, they also represent the largest potential market for mobile operators. Gayatri Murthy digs into the data so that development(More)
The linear complementarity problem (q, A) with data A ∈ R n×n and q ∈ R n involves finding a nonnegative z ∈ R n such that Az + q ≥ 0 and z t (Az + q) = 0. Cottle and Stone introduced the class of P 1-matrices and showed that if A is in P 1 \Q, then K(A) (the set of all q for which (q, A) has a solution) is a half-space and (q, A) has a unique solution for(More)
