Question: Von Neumann's results have been viewed as a special case of linear programming, where von Neumann's model uses only nonnegative matrices. The study of von Neumann's model of an expanding economy continues to interest mathematical economists with interests in computational economics. This paper has been called the greatest paper in mathematical economics by several authors, who recognized its introduction of fixed-point theorems, linear inequalities, complementary slackness, and saddlepoint duality. In the proceedings of a conference on von Neumann's growth model, Paul Samuelson said that many mathematicians had developed methods useful to economists, but that von Neumann was unique in having made significant contributions to economic theory itself.
Is there an answer to this question: What was the significance of von Neumann's model of expanding economy?

Answer: unique in having made significant contributions to economic theory itself.


Question: The earliest examples of neoclassical architecture in Hungary may be found in Vác. In this town the triumphal arch and the neoclassical façade of the baroque Cathedral were designed by the French architect Isidor Marcellus Amandus Ganneval (Isidore Canevale) in the 1760s. Also the work of a French architect Charles Moreau is the garden façade of the Esterházy Palace (1797–1805) in Kismarton (today Eisenstadt in Austria). The two principal architect of Neoclassicism in Hungary was Mihály Pollack and József Hild. Pollack's major work is the Hungarian National Museum (1837–1844). Hild is famous for his designs for the Cathedral of Eger and Esztergom.
