Abstract

The ordered fieldR(M) consists of the realsR with a transcendentalM adjoined, which is larger than any realr ∈R. Given any semi-infinite matrix (s.i.m.) interpreted as linear inequalities:u tPi≧c i, ∀ i ∈I, an arbitrary index set, it is also shown that the following are equivalent. (1) For every finiteJ ⊆I the systemu tPi≧c i,i ∈J is consistent, and (2) the s.i.m. has a solutionu ∈R(M) n. Some consequences for “duality gaps” are also given.
