Thus, it has been argued that urban design was murdered in the industrial age. Urban Politics/Governance: understanding the city as a system of linked decisionsaffluence, imminent domain, citizen participation in a democratic city; the game theory, in which people interact together according to fixed rules and produce agreed-upon outcomes, Urban Chaos: rejects previous theories of competition and posits the city as an arena of conflict, in which the city's form is the residue and sign of struggle, and also something which is shaped and used to wage it.
