This paper analyzes the complexity of the "contraction fixed point problem": compute an epsilon-approximation to the fixed point "V"*Gamma("V"*) of a contraction mapping Gamma that maps a Banach space "B-sub-d" of continuous functions of "d" variables into itself. We focus on "quasi linear...

In an electoral framework of unidimensional two-candidate spatial competition with probabilistic voting, special interest groups present candidates with schedules that give the level of campaign contribution they will make for each feasible candidate policy location. Candidates, motivated by the...
