DEBREU (Gérard).
Mathematical Economics: Twenty Papers of Gerard Debreu.
A collection of essays published in the year that Debreu was awarded the Nobel Prize in Economics, bringing together his principal essays written after the publication of his seminal Theory of Value (1959).
A large number of these technical papers pertain to what is called ‘existence theorems’, seeking to ‘relax the stringent assumptions required to prove the existence of general equilibrium under competitive conditions, while also addressing the quite separate questions of the speed at which actual economies converge a general equilibrium solution’ (Balug).
